Description
Pericom Semiconductor’s PI2EQX3201BL is a low power,
signal ReDriver. The device provides programmable
equalization, amplification, and de-emphasis by using 4 select
bits, SEL[0:3], to optimize performance over a variety of
physical mediums by reducing Inter-Symbol Interference.
PI2EQX3201BL 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 flexibility with
signal integrity of the signal before the re-driver. Whereas the
integrated de-emphasis circuitry provides flexibility 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 a channel is enabled (EN_x=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
PI2EQX3201BL also provides power management Stand-by
mode operated by a Bus Enable pin.
