PI2EQX5984

2.5/5.0Gbps 4-lane PCIe 2.0 ReDriver with Equalization & Emphasis

Product Description

The PI2EQX5984 is a low power, PCIe® compliant signal ReDriver. The device provides programmable equalization, amplification, and de-emphasis by using 8 select bits, to optimize performance over a variety of physical mediums by reducing Inter-symbol interference.

PI2EQX5984 supports eight 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 ReDriver, whereas the integrated de-emphasis circuitry provides flexibility with signal integrity of the signal after the redriver.

In addition to providing signal re-conditioning, the PI2EQX5984 also provides power management Stand-by mode operated by a Bus Enable pin.
