Product 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 flexibility with signal integrity of the PCI Express signal before the Re-Driver. Whereas the integrated de-emphasis circuitry provides flexibility 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.
