PI2EQX6804-A
6.5Gbps, 4-lane, SAS2.0/SATA3.0/XAUI ReDriver
TM
with Equalization & Emphasis
Pericom Semiconductor’s PI2EQX6804-A is a low power, SAS2,
SATA, XAUI signal ReDriver™. The device provides programmable
equalization, amplification, and emphasis by using 8 select bits,
to optimize performance over a variety of physical mediums by
reducing Inter-symbol interference.
PI2EQX6804-A supports eight 100Ω 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
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.

Redrivers with emphasis and equalization signal conditioning technology
ensure the integrity of high-frequency SAS2.0/SATA3.0 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
