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.

PI2EQX6804-A demo board 2) Configuration Control PI2EQX6804-A provides two ways configuration control depending on the state of the MODE input (PIN G5). MODE determines whether IC configuration status is from the input pins or via I2C control, when MODE is set high, the configuration input pins set the configuration operating state as stored in configuration registers, changes to these control registers are disabled and initial condition is protected from any changes to insuring a known operating state. - Page 4 SW3 location SW2 location SW1 location Figure5b SW1, SW2 and SW3 location on PI2EQX6804-A demo board Figure6 shows input equalizer selection table for Channel A and B.
