PI2EQX8864
8.0Gbps, 4-Lane PCIe
Pericom Semiconductor’s PI2EQX8864 is a low power PCIe
3.0 (8Gbps) ReDriver™. The device provides programmable
equalization, pre-emphasis, and output voltage swing control
via I
by reducing Inter-symbol interference (ISI). The PI2EQX8864
also provides advanced features such as bi-directional loop
back functionality for easy debug, a selectable signal detector
threshold, and I
The integrated equalization circuitry provides flexibility
with signal integrity of the PCIe signal before the ReDriver,
whereas the integrated pre-emphasis circuitry provides
flexibility with signal integrity of the signal after the ReDriver.
In addition to providing signal reconditioning, Pericom’s
PI2EQX8864 also provides power management stand-by mode
operated by a power-down pin.

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.
