Specifically designed to support Infrared Data Association (IrDA) IrMC low-power SIR (serial infrared) mode, the transceiver combines an infrared emitting diode (IRED) emitter, a PIN photodiode detector, a digital AC-coupled LED driver, and a receiver/decoder in a single, miniature package. The ZiLOG ZHX1200 provides an efficient implementation of the low-power SIR standard in a small footprint format. Application circuit space is also minimized, as only one capacitor is required to complete the solution. Features * * * * * * * * * Compliant to the IrDA Specification Low-Power SIR Low supply voltage range, 2.7 to 3.6 V 0.2 A (maximum) shutdown Low power, 95 A (typical) at 3.3 V Ultra small form factor (6.8 mm long x 2.8 mm wide x 2.2 mm high) External component: one capacitor Extended operating temperature range (-30 C to +85 C) ILED=35 mA at 3.6 mW/sr Meets IEC 825-1 Class 1 Eye Safety Specifications PS007110-0802 ZHX1200 Low-Power SIR (IrMC) Transceiver 2 Block Diagram Figure 1 is the block diagram for the IrMC Transceiver. Figure 1. IrMC Transceiver Block Diagram Figure 2 shows a typical application of the IrMC transceiver. PS007110-0802 ZHX1200 Low-Power SIR (IrMC) Transceiver 3 Figure 2. ZHX1200 Application Block Diagrams PS007110-0802 ZHX1200 Low-Power SIR (IrMC) Transceiver 4 Pin Description Table 1 lists the pin out for the IrMC transceiver. The pins are described in this section. Table 1. IrMC Transceiver Pin Out Pin 1 2 3 4 5 6 -- Name VCC GND SD RXD TXD LEDA TAB Function Supply voltage Ground Enables SD mode Receiver output Transmitter input IRED anode Shield ground I/O -- -- I O I -- -- VCC Positive Supply (Power) Connect to positive power supply (2.7-3.6 V). Place a 0.33-F ceramic bypass capacitor as close as possible to the VCC pin. GND Ground (Power) Connect to ground of the power supply. A solid ground plane is recommended for proper operation. TAB (Shield) The Shield tab must be soldered to the ground plane. TXD Transmit Data (Input, active high) This CMOS input is used to transmit serial data. PS007110-0802 ZHX1200 Low-Power SIR (IrMC) Transceiver 5 TXD has integrated digital AC coupling; therefore, no external AC-coupling components are required for input signals between GND and VCC. This pin can never float while the device is under power. RXD Receive Data (Output, active low) This output indicates received serial data. It is a CMOS output driver capable of driving a standard CMOS or LSTTL load. No external resistor is required. SD Shutdown (Input, active high) This input is used to place the integrated circuit into shutdown mode. Maximum current draw in shutdown mode is 0.2 A. Module shutdown current might be limited by the choice of capacitor used from VCC1 to ground. LEDA IRED Driver Anode (Power) This output is internally connected to the LED anode and is connected to the supply voltage. Current to the LED must be limited to a maximum of 50 mA (20% duty cycle maximum). The voltage range on this pad is 2.7-3.6 volts. Electrical and Timing Specifications Table 2, Table 3, and Table 4 list the electrical and timing specifications. Table 2.

Moisture Prevention Guidelines In order to avoid moisture absorption during transportation and storage, ZHX1200 reels are packed in aluminum envelopes (see Figure 13) that contain a desiccant with a humidity indicator. While this packaging is an impediment to moisture absorption, it is by no means absolute, and no warranty is implied. The user should store these parts in a controlled environment to prevent moisture entry. Please read the label on the aluminum bag for indicator instructions. ALUMINUM ENVELOPE DESICCANT REEL LABEL Figure 13. IrMC Transceiver Packaging Baking Parts that have been stored over 12 months or unpacked over 72 hours must be baked under the following guidelines. Reels 60 C for 48 hours or more Loose Parts * * * 100 C for 4 hours or more or 125 C for 2 hours or more or 150 C for 1 hour or more PS007110-0802 ZHX1200 Low-Power SIR (IrMC) Transceiver 15 Taping Specifications (in Accordance with JIS C 0806) Figure 14 shows the reel dimensions, and Figure 15 shows the tape dimensions and configuration.
