Description
Pericom Semiconductor’s PI2EQX5804 is a low power,
PCI-express compliant signal re-driver. The device provides
programmable equalization, amplifi cation, and de-emphasis by
using 8 select bits, to optimize performance over a variety of
physical mediums by reducing Inter-symbol interference.
PI2EQX5804 supports eight 100-Ohm 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 fl exibility with
signal integrity of the PCI-express signal before the re-driver,
whereas the integrated de-emphasis circuitry provides fl exibility
with signal integrity of the signal after the re-driver.
In addition to providing signal re-conditioning, Pericom’s
PI2EQX5804 also provides power management Stand-by mode
operated by a Power Down pin.
