PI2EQX6812

6.5Gbps 2-Lane (4-channel)SAS2/SATA/XAUI ReDriver™ with

Equalization & De-emphasis

Pericom Semiconductor’s PI2EQX6812 is a low power, SAS2,

2-lane (4 differential channels) SATA, XAUI signal ReDriver™.

The device provides programmable equalization, amplifica-

tion, and de-emphasis by either pin strapping option or I

Control, to optimize performance over a variety of physical

mediums by reducing Inter-symbol interference.

PI2EQX6812 supports four 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 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

PI2EQX6812 also provides power management Stand-by

mode operated by a Power Down pin, or through I

When the input is idle, the device goes to power saving slum-

ber mode
