PI2EQX5984
5.0Gbps 4-Lane PCIe
Pericom Semiconductor’s PI2EQX5984 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.
PI2EQX5984 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
PI2EQX5984 also provides power management Stand-by mode
operated by a Bus Enable pin.

Figure1
Redrivers with emphasis and equalization signal conditioning technology ensure
the integrity of high-frequency PCIe signals by opening closed signal eyes to
recover data and meet strict compliance testing requirements. Increased signal
margin also supports longer drive lenghts over even low-quality cables.
