Product Databrief

Pericom Semiconductor’s PI2EQX5964 (or 5904) is a low

power, PCIe

high speed serial signals such as serdes backplane and non

protocol specific protocols. 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.

PI2EQX5964 supports eight 100W 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

PI2EQX5964 also provides power management Stand-by mode

operated by a Bus Enable pin.

Target markets for this ReDriver are networking, embedded,

industrial, server and storage applications, including non-

protocol-specific and high-speed signal applications.

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.
