Description
Pericom Semiconductor’s PI2EQX3232B is a low power, signal
Re-Driver. The device provides programmable equalization,
amplifi cation, and de-emphasis, to optimize performance over a
variety of physical mediums by reducing Inter-Symbol Interference
(ISI). PI2EQX3232B supports four 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. Whereas the
integrated de-emphasis circuitry provides fl exibility with signal
integrity of the signal after the Re-Driver.
A low-level input signal detection and output squelch function
is provided for all four channels. 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 output driver
switches off, and the pin is pulled to VDD via a high impedance
resistor. 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
PI2EQX3232B also provides power management Stand-by mode
operated by an Enable pin.
