www.DataSheet4U.com PI2EQX3211B 3.2Gbps 2 Differential Channel Serial Re-driver with Equalization, Squelch and Flow-Through Pinout Features SATA s/m output drive Two 3.2Gbps differential channels Adjustable Receiver Equalization 100Ω Differential CML I/O’s Input signal level detect and squelch for each channel Low Power (100mW per Channel) Stand-by Mode – Power Down State VCC Operating Range: 1.8V ±0.1V Packaging (Pb-free & Green): — 20-lead SSOP Description Pericom Semiconductor’s PI2EQX3211B is a low power, signal re-driver. The device provides programmable equalization, by using 2 select bits, EQA and EQB, to optimize performance over a variety of physical mediums by reducing Inter-Symbol Interference. PI2EQX3211B supports two 100 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 flexibility with signal integrity of the signal before the re-driver. Whereas the integrated de-emphasis circuitry provides flexibility with signal integrity of the signal after the re-driver. A low-level input signal detection and output squelch function is provided for each channel. Each channel operates fully independantly. When the channels are enabled (EN=1) and operating, that channels input signal level (on xI+/-) determines whether the output is enabled. If the input level of the channel falls below ...
