New Product Databrief
Pericom Semiconductor’s PI3EQX6801 is a low power,
1.5V/3.3V, 6.5Gbps, SATA/SAS signal ReDriver™. The device
provides programmable equalization, to optimize performance
over a variety of physical mediums by reducing Inter-Symbol
Interference.
PI3EQX6801 supports two 100Ω 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 flexibility with
signal integrity of the signal before the ReDriver.
A low-level input signal detection and output squelch function
is provided for each channel. Each channel operates fully
independently. When the channels are enabled (x_EN#=0)
and operating, that channels input signal level (on xI+/-)
determines whether the output is active. If the input signal level
of the channel falls below the active threshold level (Vth-) then
the outputs are driven to the common mode voltage.
Each lane can be powered-down if x_EN# =1, and when
A_EN# and B_EN# are both high, the device enters a low
power standby mode.

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
