Description
Pericom Semiconductor’s PI2EQX3421 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. PI2EQX3421 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 sig-
nals across other distant data pathways on the user’s platform.
The integrated equalization circuitry provides flexibility with
signal integrity of the signal input to ReDriver.
A low-level input signal detection and output squelch function is
provided for each channel. Each channel operates fully indepen-
dently. When the channels are enabled (CE=1) and operating,
that channels input signal level (on XIN+/-) determines whether
the output is enabled. 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, Pericom’s PI2EQX3421 also
provides power management Stand-by mode operated by the
Chip Enable (CE) pin.
