PI2EQX6804-ANJE EvalBoard Rev.A User Guide
Introduction
Pericom Semiconductor’s PI2EQX6804-A is a low power, SAS2, SATA, XAUI signal Re-Driver. The device provides
programmable equalization, amplification, and emphasis by using 8 elect bits, to optimize performance over a variety
of physical mediums by reducing Inter-Symbol Interference.
PI2EQX6804-A supports eight 100-Ohm Differential CML data I/O’s between the Protocol ASIC to a switch fabric,
across a backplane, or to extend the signals across other distant data pathways on the user’s platform.
The integrated equalization circuitry provides fl edibility with signal integrity of the signal before the re-driver, whereas
the integrated emphasis circuitry provides flexibility with signal integrity of the signal after the reDriver.
In addition to providing signal re-conditioning, Pericom’s PI2EQX6804-A also provides power management Stand-by
mode operated by a Power Down pin.
This design guide describes how to use PI2EQX6804-A SATA ReDriver in the demo board. Figure1 shows top view
and bottom view of PI2EQX6804-A demo board. This demo board is just for SAS application using SAS connector.
