New Product Databrief

Pericom Semiconductor’s PI3EQX4951ST is a low power, signal

ReDriver™. The device provides programmable equalization,

to optimize performance over a variety of physical mediums by

reducing Inter-Symbol Interference. PI3EQX4951ST supports two

100W 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 (EN=1) 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.

In addition to signal conditioning, when EN = 0, the device

enters a low power standby mode.
