Description
Pericom Semiconductor’s PI2EQX5864D is a low power, PCIe
compliant signal redriver. The device provides programmable
equalization, amplification, and de-emphasis by using 8 select
bits, to optimize performance over a variety of physical mediums
by reducing Inter-symbol interference.
PI2EQX5864D 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 flexibility with
signal integrity of the PCI Express signal before the ReDriver™,
whereas the integrated de-emphasis circuitry provides flexibility
with signal integrity of the signal after the redriver.
In addition to providing signal re-conditioning, Pericom’s
PI2EQX5864D also provides power management Stand-by mode
operated by a Bus Enable pin.
