PI3EQX3811C supports two 100-ohm differential cml data i/o?s between the protocol asic to a switch fabric, across a backplane, or to extend the signals across other distant data pathways on the user?s platform. the integrated equalization circuitry provides exibility with signal integrity of the signal before the redriver. whereas the integrated de-emphasis circuitry provides exibility with signal integrity of the signal after the redriver. a low-level input signal detection and output squelch function is provided for each channel. each channel operates fully independently. when the channels are enabled (en=1) and operating, a channel?s input signal level (on xi+/-) determines whether the output is enabled. if the input level of the channel falls below the active threshold level (vth-) then the outputs are driven to the common mode voltage. in addition to providing signal re-conditioning, pericom?s PI3EQX3811C also provides power management stand-by mode operated by the enable pin. block diagram PI3EQX3811C 3.3v, 1-port, sata2 i/m redriver ? with equalization and output emphasis pin description (top-side view) xl+ xl- xo+ xo- limiting amp equalizer emx power management en - repeated 2 times - cml cml signal detection ema vdd ai+ ai- gnd vdd bo+ bo- gnd emb en vdd ao+ ao- gnd vdd bi+ bi- gnd nc 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 09-0046
