Description
Pericom Semiconductor’s PI2EQX4432D is a low power,
PCI Express compliant signal Re-Driver. The device provides
programmable equalization, to optimize performance by reducing
Inter-Symbol Interference (ISI). PI2EQX4432D supports two
100
Ohm 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 channels input signal level (on xl+/-) 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.
In addition to providing serial re-conditioning, Pericom's
PIEQX4432D also provides a power management Stand-by mode
operated by the enable pins.
