www.DataSheet4U.com PI2EQX3201 3.2Gbps 2 Differential Channel Serial Re-driver with built-in Equalization and De-emphasis Features Two 3.2Gbps differential signal Adjustable Transmiter De-Emphasis & Amplitude Adjustable Receiver Equalization One Spread Spectrum Reference Clock Buffer Output 100Ω Differential CML I/O’s Low Power (100mW per Channel) Stand-by Mode – Power Down State VCC Operating Range: 1.8V ±0.1V Built in Clock Buffer Packaging (Pb-free & Green): — 36-pad TQFN (ZF36) Description Pericom Semiconductor’s PI2EQX3201 is a low power, signal re-driver. The device provides programmable equalization, amplification, and de-emphasis by using 4 select bits, SEL[0:3], to optimize performance over a variety of physical mediums by reducing Inter-symbol interference. PI2EQX3201 supports two 100 Differential CML data I/O’s between the Protocol ASIC to a switch fabric, across a backplane, or extends 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. In addition to providing signal re-conditioning, Pericom’s PI2EQX3201 also provides power management Stand-by mode operated by a Bus Enable pin.
