Description
Pericom Semiconductor’s PI2EQX3431 is a low power, signal
Re-Driver. The device provides programmable equalization,
to optimize performance over a variety of physical mediums
by reducing Inter-Symbol Interference. PI2EQX3431 supports
two 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 exibility with
signal integrity of the signal before the re-driver.
A low-level input signal detection and output squelch function
is provided for each channel. Each channel operates fully
independantly. When the channels are enabled (CE=1) and
operating, that channels input signal level (on xIN+/-) 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 CE = 0, the device
enters a low power standby mode.
