3.2Gbps 2 Differential Channel Serial Re-driver
1
with built-in Equalization and De-emphasis
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.
