Description
Pericom Semiconductor’s PI2EQX3211A is a low power, signal
re-driver. The device provides programmable equalization, by
using 2 select bits, EQA and EQB, to optimize performance
over a variety of physical mediums by reducing Inter-Symbol
Interference. PI2EQX3211A 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 exibility with
signal integrity of the signal before the re-driver. Whereas the
integrated de-emphasis circuitry provides exibility with signal
integrity of the signal after 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 (EN=1) and
operating, that channels input signal level (on xI+/-) determines
whether the output is enabled. If the input level of the channel
falls below the active threshold level (Vth-) then the outputs are
driven to the common mode voltage.
In addition to providing signal re-conditioning, Pericom’s
PI2EQX3211A also provides power management Stand-by
mode operated by the Enable pin.
