PI2EQX5964

Product Description

The PI2EQX5964 (or 5904) is a low power, PCIe® compliant signal redriver also suitable for other high speed serial signals such as serdes backplane and non protocol specific protocols. 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.

PI2EQX5964 supports eight 100W 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, Pericom’s PI2EQX5964 also provides power management Stand-by mode operated by a Bus Enable pin.

Target markets for this ReDriver are networking, embedded, industrial, server and storage applications, including non-protocol- specific and high-speed signal applications.
