Description
Pericom Semiconductor’s PI2EQX4402 is a low power, PCI
Express compliant signal re-driver. The device provides
programmable equalization, amplification, and de-emphasis
by using 7 select bits, SEL[0:6], to optimize performance
over a variety of physical mediums by reducing Inter-symbol
interference. PI2EQX4402 supports four 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 PCI Express signal before the re-driver.
Whereas the integrated de-emphasis circuitry provides flexibility
with signal integrity of the PCI Express signal after the re-driver.
In addition to providing signal re-conditioning, Pericom’s
PI2EQX4402 also provides power management Stand-by mode
operated by a Bus Enable pin.
