I2C-BUS PROTOCOL Addressing and data bytes
TDA9615H
For programming the device (write mode) seven data byte registers are available; they are addressable via eight subaddresses. Automatic subaddress incrementing enables the writing of successive data bytes in one transmission. During power-on, data byte registers are reset to a default state by use of a Power On Reset (POR) circuit which signal is derived from the internally generated I2C-bus supply voltage (V5OUT; pin 38). For reading from the device (read mode) one data byte register is available without subaddressing. Table 1 TDA9615H addresses and data bytes DATA BYTE Write mode Slave address byte (B8H) Subaddress bytes (00H to 07H) Control byte (subaddress 00) Select byte (subaddress 01) Input byte (subaddress 02) Output byte (subaddress 03) Left volume byte (subaddress 04) Right volume byte (subaddress 05) Volume byte (subaddress 06) Power byte (subaddress 07) Read mode Slave address byte (B9H) Read byte Notes 1. Use of subaddress F0H to F7H (1111 0XXX) instead of 00H to 07H (0000 0XXX) disables the automatic subaddress incrementing allowing continuous writing to a single data byte register. 2. The state of unused read bits are not reliable; their state may change during development. Table 2 Status of data bytes after POR DATA BYTE Control byte Select byte Input byte Output byte Left volume byte Right volume byte Power byte Note 1. For eventual future compatibility it is advised to keep unused write bits equal to POR state. 1997 Jun 16 9 1 0 0(1) 0 0(1) 0(1) 0 0 0 0 0 1 1 0 0 1(1) 0 0 0 0 0 0 1(1) 0 0 0 0 0 ADDRESS 1 0 1 0 0 0 0(1) 1 0 1 0 0 0 0(1) 0 0 1 0 0 0 0(1) 0 0 0(1) 1 0 0 0(1) 1 CALR 0 AUTN 1 0(2) 1 POR 1 0(2) 0 1(2) 0 0(2) 1 0(2) 1 0(1) AFM DOS1 i7 LOH I7 r7 0 0(1) DOC DOS0 IS2 OSN VLS VRS 1 0(1) SHH s5 IS1 OSR VL5 VR5 1 0(1) DETH s4 IS0 OSL VL4 VR4 1 0 NTSC NIL3 NS2 EOS VL3 VR3 0 0 or 1 MUTE NIL2 NS1 LOS VL2 VR2 0 0 or 1 STBP NIL1 NS0 DOS VL1 VR1 0 0 or 1 STBA NIL0 i0 RFCM VL0 VR0 ADDRESS

2. Auto-normal function: if during hi-fi `playback' mode no FM carrier is detected at FMIN (pin 37) the `Normal' mode audio signal (LININ; pin 21) is automatically selected by the output select function. a) Hi-fi carrier detection time (i.e. auto-normal release time) can be selected via bit DETH: `fast' mode: 1 to 2 HID periods (33 to 66 ms NTSC, 40 to 80 ms PAL) `slow' mode: 7 to 8 HID periods (233 to 267 ms NTSC, 280 to 320 ms PAL). b) The status of hi-fi detection can be monitored via the I2C-bus; see bit AUTN of the read byte (see Table 31). c) If muting is required instead of automatic selection of the `Normal' mode audio signal the normal input level function should be set to mute; see bits NIL3 to NIL0 of the select byte. 1997 Jun 16 11

NTSC(1) 0 1 Notes
1. Bit NTSC selects between the system standard settings for NTSC and PAL (SECAM) use. The auto-calibration function uses the system standard HID frequency of 29.97 Hz for NTSC and 25 Hz for PAL. After calibration bit NTSC allows immediate switching between the NTSC and PAL system standard. 2. POR. Table 8 Bit MUTE MODE - mute(2) DESCRIPTION power mute function released; mute switches open power mute function activated; mute switches closed
MUTE(1) 0 1 Notes
1. Bit MUTE controls the line and RFC output mute switches at pins 13, 14 and 17 (power mute function). Power mute is also automatically activated at supply voltage power-up or power-down (VCC; pin 35). 2. POR. Table 9 STBP 0 0 1(4) Notes 1. POR. 2. By selecting STBA = 1 the TDA9615H is switched to low-power `active standby' mode. To reduce power consumption most circuits are switched off. RFC, line and decoder outputs however remain active. This way the direct audio selections offered via the line output select and decoder output select functions (bits LOS and DOS of the output byte) remain operable in this mode. The `Output Select' mode signal is muted. 3. Calibration and I2C-bus registers are not affected by using `active standby' or `passive standby' mode. 4. By selecting STBP = 1 the TDA9615H is switched to minimum power `passive standby' mode. All circuits except power mute, I2C-bus and the line input reference buffer (voltage at pins 1 to 10 and 44) are switched off for minimum power consumption. Use of the power mute function (bit MUTE of control byte) ensures pop-free switching of the line and RFC output to and from `passive standby' mode. To obtain minimum power consumption the power mute function should be de-activated again during `passive standby' mode. 5.

AUX input signal (L) and selection of hi-fi output signal (R) LININ input (linear audio) AUXL and AUXR input (e.g. camcorder input)
1. Bits IS2, IS1 and IS0 select the input signal which is led to the volume controls of the hi-fi processing and generally via the normal select function to the linear audio circuit (LINOUT; pin 20). 2. POR. 3. `Dub Mix' is a special selection for linear audio use supporting audio dubbing (a video recorder feature mode for sound recording of linear audio only). `Dub Mix' connects the AUX input signal to the left channel (12AUXL + 12AUXR) and the hi-fi output signal to the right channel (generally 12hi-fi left + 12hi-fi right but also hi-fi left or hi-fi right can be selected). `Dub Mix' also changes part of the `Output Select' mode settings to `Normal' mode for monitoring of the linear audio recording (see control bits OSN, OSR and OSL of the output byte for `Dub Mix' mode input and output selection). Table 15 Bits NS2, NS1, NS0; note 1 NS2 0 0 0 0 1 1 1 1 Notes 1. With bits NS2, NS1 and NS0 the input signal is selected which is available at the LINOUT output (pin 20) for connection to an external linear audio circuit. The signal selected with the input select function (via bits IS2, IS1 and IS0) is available in the following ways: a) Left and right channel combined, optional including hi-fi volume control (12hi-fi left + 12hi-fi right). b) Left channel only (language I), optional including left channel volume control. Furthermore the SAP input (pin 44), tuner input (pins 1 and 2) or EXT2 input (pins 7 and 8) can be selected independently. Also a mute setting is available. 2. POR.

Table 17 Bit LOH; note 1 LOH 0 1 Notes 1. An additional 1 dB amplification can be selected for line and decoder outputs LINEL, LINER, DECL and DECR (pins 15, 16, 18 and 19). 2. POR. Table 18 Bits OSN, OSR and OSL; notes 1 and 2 OSN 0 0 0 0 1 1 1 1 Notes 1. When no hi-fi signal is found on tape during `playback' mode the auto-normal function is activated; all output select function modes except `mute' will be overruled and changed to `Normal' mode. If muting of the hi-fi sound is desired instead of selecting linear audio the normal input level (bits NIL3 to NIL0 of the select byte) should be set to mute. Activation of the auto-normal function can be monitored by reading bit AUTN of the read byte. 2. If `Dub Mix' mode is selected via the input select function (see control bits IS2, IS1 and IS0 of the input byte) functionality of the modes `Mix-Left', `Mix-Right' and `Mix-Stereo' are changed to support audio dubbing input mixing. Hi-fi channel selection is offered for the input and normal sound is available at the output for monitoring of the linear audio recording. See also Table 19. 3. POR.

Table 27 Bit CALS; note 1 CALS(2) 0 1 Notes 1. Pin 39 (ENVOUT) or bit CALR of the read byte can be monitored to check for successful completion of the calibration. It is advised to keep CALS logic 1 after calibration to ensure a reliable CALR state. 2. After a change of bit CALS from logic 0 to logic 1, an automatic frequency calibration is performed setting hi-fi modem, band-pass filter and noise reduction. Use of auto-calibration is only needed after power-up of the supply voltage (POR). 3. POR. Table 28 Bit VCCH; notes 1 and 2 VCCH 0 1 Notes 1. To maximize the output drive when using 12 V supply voltage (VCC; pin 35), the DC level of outputs LINEL, LINER, DECL and DECR (pins 15, 16, 18 and 19) can be changed using bit VCCH. 2. Use of the power mute function (bit MUTE of the control byte) ensures disturbance-free switching of the line output signal when setting VCCH after power-up. 3. POR.

Table 30 Bit PORR; note 1 PORR 0 1 Notes MODE - (note 2) POR reset - reset of POR signal bit DESCRIPTION
TDA9615H
1. Bit POR of the read byte can be used to detect the occurrence of a power-on reset situation (bit POR reads logic 1 in case the I2C register contents equal the POR default state). When applying bit POR this way, PORR should be used after a power-on reset to force a reset of the POR read bit state to logic 0. 2. POR. Read byte (device state information) Table 31 Bits of read byte BIT CALR AUTN POR calibration ready; see Table 32 auto-normal; see Table 33 power-on reset; see Table 34 DESCRIPTION
Table 32 Bit CALR; notes 1 and 2 CALR 0 1 Notes 1. Bit CALR = 0 indicates the device is not calibrated. After an automatic calibration is started by setting bit CALS of the power byte the end of calibration is signalled by this bit. If for some reason a calibration cannot be completed (e.g. no HID signal available or hi-fi processing is in `playback' mode) CALR remains logic `0'. If calibration is lost due to a power-on reset situation CALR will return to logic 0 as well. 2. Also the envelope output (pin 39) can be used to check for end of calibration. Table 33 Bit AUTN; notes 1 and 2 AUTN 0 1 Notes 1. When hi-fi processing is in `playback' mode but no hi-fi carrier input signal is detected the auto-normal function is activated. Auto-normal overrules the `Output Select' mode setting, selecting normal sound (i.e. linear audio) instead of hi-fi. The state of this auto-normal function can be checked via bit AUTN. 2. The auto-normal function is only active (bit AUTN = logic 1) for hi-fi `playback' mode (bit AFM = 0); during `record' or `loop-through' mode bit AUTN is always logic 0. audio FM signal is detected at FM input no audio FM signal detected; normal sound is selected instead of hi-fi DESCRIPTION device is not calibrated device has completed auto-calibration DESCRIPTION

Table 34 Bit POR; notes 1 and 2 POR 0 1 Notes DESCRIPTION I2C-bus bit state differs from power-on reset state I2C-bus bit state equals power-on reset state
TDA9615H
1. At power-on or during a power voltage dip, an internal power-on reset signal is generated which resets the I2C-bus data bits to a predefined state. When the internal data bits are found to be in POR state (due to an actual power-on reset but also if set via the I2C-bus) bit POR signals logic 1. 2. Using the POR bit to detect the occurrence of a power-on reset requires bit PORR to be set logic 1 after power-up. Setting bit PORR forces the POR bit to logic 0 independent of other I2C-bus bit settings. After calibration is completed also the CALR bit can be used to detect a power-on reset; calibration will be lost in such situation which is signalled by CALR = 0.

Automatic calibration; see Fig.7 By means of bit CALS (power byte) the integrated auto-calibration system is activated. By adjusting the carrier frequencies, band-pass filters and noise reduction filters auto-calibration ensures that the hi-fi processing always is in accordance with the VHS hi-fi system standard. Calibration is only needed after start-up of the video recorder; as long as the supply voltage (pin 35) is available calibration settings remain stable. Auto-calibration is performed with the device in hi-fi `loop-through' mode, no standby or test mode should be active (auto-calibration demands bit settings AFM = 1, STBP = 0, STBA = 0 and TEST = 0). After setting bit CALS (power byte) to logic 1 auto-calibration is started. Calibration is performed fully automatically, using the HID input signal as a reference. Calibration of the oscillator frequencies is performed by measuring the number of oscillator cycles within one HID HIGH period and comparing this with an internal value stored in ROM. Four different ROM values are available for NTSC or PAL (SECAM) system calibration of both the left and right channel carrier. In case of NTSC calibration a special routine is active for the right channel carrier calibration resulting in a frequency difference between the left and right channel carrier of
TDA9615H
approximately 401.2 kHz. This value effectively reduces the crosstalk from hi-fi carriers to the video colour signal as present during `playback' mode using Extended Play (EP) tape speed. NTSC calibration uses the standard 29.97 Hz (i.e. 16.683 ms) HID signal where PAL calibration uses the standard 25 Hz (i.e. 20 ms) HID signal. The maximum frequency error after auto-calibration is 5 kHz assuming a HID HIGH-time error of maximum 5 s. To realize NTSC EP optimization within 2 kHz, HID jitter should not exceed 1 s. In general the crystal based HID signal available in the video recorder can be used without modification. After calibration of the oscillators, the band-pass filters are calibrated together with the integrated `weighting' and `FM de-emphasis' filter of the noise reduction. The total auto-calibration time needed is 17 HID cycles or less. End of calibration is signalled by bit CALR of the read byte. The envelope output can also be used to monitor calibration; for this purpose ENVOUT (pin 39) is forced >2.5 V during calibration. The audio signal to the audio envelope (level meter) function should be muted; otherwise the audio envelope output may be >2.5 V as well making it impossible to detect end of calibration via the ENVOUT pin.

After a calibration in `NTSC' or `PAL' mode the oscillators and band-pass filters can be switched between NTSC and PAL system frequencies without the need for additional calibration. Switching between these system modes is executed immediately and can be done in any operational mode. Frequency accuracy of switching is 100 kHz 3 kHz for both carriers. For `record' mode however it is advised to use re-calibration after system switching; this to obtain the best possible frequency accuracy. A new auto-calibration can be started by first resetting bit CALS to logic 0 followed by setting bit CALS to logic 1 again.

carrier level (e.g. auto-tracking). At the microcontroller only one A/D converter input is needed for reading of all necessary information. During `playback' mode I2C-bus bit EOS offers selection between audio or carrier level information. Audio level information is always output during `loop-through' mode and `record' mode however now EOS offers a fixed selection of hi-fi stereo (i.e. independent of the `Output Select' mode setting); helpful when audio level information is used by the microcontroller for controlling the hi-fi record volume.

Audio envelope uses time multiplexing to output both left and right channel audio level. A peak hold function and dynamic range compression (square root function) are included for easy read-out. The peak hold function as well as left and right channel multiplexing is controlled by the HID input signal (pin 40).
The HF envelope output signal is continuous and derived from the left channel carrier. HF envelope shows a logarithmic characteristic.

Power mute; see Fig.12 Without countermeasures switching of the power supply voltage (VCC; pin 35) or use of the built-in `passive standby' mode causes strong disturbances on the output pins because of the rise or drop of the output's DC voltages. The TDA9615H includes three integrated mute switches to block such disturbances and avoiding the need of an external mute circuit. By connecting the power mute switches behind the line and RFC output capacitors pop-free line and RFC output signals are realized. Power muting is active when control byte bit MUTE = 1. Because this also is the POR default state, muting is automatically activated when the power supply voltage is switched on. The integrated mute switches (MUTEC, MUTEL and MUTER; pins 13, 14 and 17) are closed, forming a low impedance path to ground. Furthermore the line and RFC outputs (RFCOUT, LINEL and LINER; pins 12, 15 and 16) are current limited to 1 mA to achieve good attenuation without the need for a series resistor between output and mute switch. Although the decoder outputs (DECL and DECR; pins 18 and 19) have no integrated muting these are current limited also for use with the integrated mute switches or to assist possible external muting.
TDA9615H
After the output DC voltage is settled the power mute function can be deactivated by selecting MUTE = 0. Now the mute switches are opened showing a high impedance of 100 k to ground and output current limiting is deactivated. Note that the time needed for output DC settling is proportional to the output capacitor value used; with a 10 F capacitor a safe mute time to use is 200 ms (i.e. tmute = C x 20000). Using such controlled muting very good performance is achieved for power-up, power-down and `passive standby' mode switching. At a sudden supply power loss however (e.g. mains power plug pulled) there may be no time to activate the power mute function via the I2C-bus. A power-down detector however instantly activates the power mute function in case the supply voltage falls below 7 V (auto-mute). For proper muting supply voltage drop rate should not exceed 1 V/10 ms.

Do not set MUTE and change STBP at the same time; to avoid output glitches power muting should precede the switching of `passive standby' mode. Power muting takes up approximately 4 mA supply current, so to realize the minimum power consumption of `passive standby' mode muting has to be deactivated. Note also the use of `passive standby' mode to initiate a controlled power-off switching. Iref resistor The external resistor at pin 28 defines internal reference currents and determines temperature stability of the circuits adjusted by the auto-calibration function.
TDA9615H
The external resistor should have the following dimensions: value = 39.0 k 2%; temperature coefficient = 50 ppm/K. Standard hi-fi audio level Using the application circuit as proposed in Fig.6, the standard FM deviation of 50 kHz equals a 1 kHz audio signal of -8 dBV line output level (LOH = 0). A different standard audio level can be selected by changing the external filter components of the noise reduction at pins 24 and 32 (EMPHL and EMPHR); standard audio level changes proportional to the impedance of the external de-emphasis filter; see Table 36.

The RFC output can be muted by setting of bit RFCM = 1. When applying this mute the AGC control is reset by discharging the capacitor at pin 11 (RFCAGC). Audio dubbing TDA9615H includes unparalleled functionality supporting the audio dubbing function of hi-fi video recorders. Audio dubbing is a feature mode for recording of new sound material on the linear audio track (i.e. normal sound) of an existing recording. Audio dubbing can be used in two different ways. OUTPUT MIX A new, partly, recording is made on the linear audio track; afterwards during `playback' mode the new linear audio and the original hi-fi sound are combined. This way hi-fi stereo quality remains and linear audio is only partly used e.g. for speech only (commentary track). However there is no control over the original (hi-fi) sound. `Playback' mode mixing of hi-fi and normal sound is supported by the output select function modes `Mix-Left', `Mix-Right' and `Mix-Stereo' (OSN, OSR and OSL of the output byte) creating a fixed output signal of 1 hi-fi left + 1 normal. 2 2 INPUT MIX
TDA9615H
A new, complete, recording is made on the linear audio track; afterwards `playback' mode uses linear audio sound only. This way hi-fi stereo quality is lost but there is total freedom in defining the new material. Furthermore this way `playback' mode is no longer restricted to hi-fi video recorders with output mix option. Selection `Dub Mix' mode of the input select function, when combined with selection `Volume' mode of the normal select function, changes the circuit into a mixing desk. A new linear audio recording can be created mixing together new and original sound. By use of the left and right channel volume controls continuous control is offered over amplitude and ratio mix of the AUX input signal (e.g. a microphone input) and the original hi-fi `playback' mode sound. This functionality is realized by internal connection of the AUX input pair to the left channel volume control and by internal connection of the hi-fi output signal pair to the right channel volume control. For output and hi-fi selection the `Dub Mix' mode uses, and partly overrules, the output select function settings. Output select function modes `Mix-Left', `Mix-Right' and `Mix-Stereo' make the normal sound available at the line outputs for monitoring of the `Dub Mix' mode recording.
Table 37 Input select function is set to `Dub Mix' mode (IS2, IS1, IS0 = 101); note 1 OUTPUT SELECT MODE Mute Left Right Stereo Normal Mix-Left Mix-Right Mix-Stereo Note 1. Modes shown in bold are the most used modes. Output select function mode `Mix-Stereo' is the setting generally used for audio dubbing. In combination with setting the normal select function to `Volume' mode user control over amplitude and ratio is offered for the AUX and hi-fi signal as follows: (14AUXL + 14AUXR) x volume left + (14hi-fi left + 14hi-fi right) x volume right. Switching hi-fi to a mode other than `playback' or selection of output select function mode `Normal' should be avoided; using these settings a signal loop can be closed from output to input possibly leading to audio oscillation. For the same reason auto-normal switching is not active during `Dub Mix' mode; in case no hi-fi input signal is detected the hi-fi sound is muted. 36 OSN 0 0 0 0 1 1 1 1 OSR 0 0 1 1 0 0 1 1 OSL 0 1 0 1 0 1 0 1 DUB MIX INPUT SELECTION DUB MIX OUTPUT SELECTION LEFT CHANNEL RIGHT CHANNEL mute hi-fi left hi-fi right stereo normal normal normal normal aux stereo aux stereo aux stereo aux stereo aux stereo aux stereo aux stereo aux stereo mute hi-fi left hi-fi right stereo normal hi-fi left hi-fi right hi-fi stereo

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all QFP packages. The choice of heating method may be influenced by larger plastic QFP packages (44 leads, or more). If infrared or vapour phase heating is used and the large packages are not absolutely dry (less than 0.1% moisture content by weight), vaporization of the small amount of moisture in them can cause cracking of the plastic body. For more information, refer to the Drypack chapter in our "Quality Reference Handbook" (order code 9397 750 00192). Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. Wave soldering
TDA9615H
Wave soldering is not recommended for QFP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. If wave soldering cannot be avoided, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. Even with these conditions, do not consider wave soldering the following packages: QFP52 (SOT379-1), QFP100 (SOT317-1), QFP100 (SOT317-2), QFP100 (SOT382-1) or QFP160 (SOT322-1). During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
