PI2EQX5904
5.0Gbps, 4-Lane PCIe^® 2.0 ReDriver^TM with Equalization and Emphasis
Pericom Semiconductor’s PI2EQX5904 (or 5964) is a low
power, PCIe^® compliant signal redriver also suitable for other
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-signal interference.
PI2EQX 5904 supports eight 100W Differential CML data I/O’s
between the Protocol ASIC to a switch fabric, across a backplane,
or extends the signal across other distant data pathways on the
user platform. PI2EQX5904 compensates signal insertion loss
at designated BER issued by PCIe2.0 endpoint device.
The integrated equalization circuitry provides flexibility with the
signal integrity of the PCIe 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
PI2EQX5904 also provides power management Stand-by mode
operated by a Power Down 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.
