Description
Pericom Semiconductor’s PI2EQX4402D is a low power,
PCI Express compliant signal Re-Driver. The device provides
programmable equalization, amplication, and de-emphasis
by using 7 select bits, SEL[0:6], to optimize performance
over a variety of physical mediums by reducing Inter-symbol
interference. PI2EQX4402D supports four 100 Differential CML
data I/O’s between the Protocol ASIC to a switch fabric, across
a backplane, or extends the signals across other distant data
pathways on the user’s platform.
The integrated equalization circuitry provides exibility with
signal integrity of the PCI Express signal before the Re-Driver.
Whereas the integrated de-emphasis circuitry provides exibility
with signal integrity of the PCI Express 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 channel input signal level (on xl+/-) determines
whether the output is enabled. If the innput 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.
In addition to providing signal re-conditioning, Pericom’s
PI2EQX4402D also provides power management Stand-by mode
operated by an Enable pin. A differential clock buffer is provided
for test and other system requirements. This clock function is not
used by the data channels.
