.. 5.0Gbps 4-Lane PCIe® 2.0 Re Driver™ with Equalization & Emphasis Features - - - - - - - - - - - - - Up to 5.0Gbps PCIe® 2.0 Serial Re Driver™ Supporting 8 differential channels or 4 lanes of PCIe Interface Pin strapped and I2C configuration controls Adjustable receiver equalization Adjustable transmitter amplitude and de-emphasis Variable input an output termination 1:2 channel broadcast Channel loop-back Electrical Idle fully supported Receiver detect and individual output control Single supply voltage, 1.2V ± 0.05V Power down modes Packaging: 100-contact LBGA, Pb-free & Green Description Peri Semiconductor’s PI2EQX5804C is a low power, PCIe® pliant signal Re Driver™. 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. PI2EQX5804C 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 PCIe signal before the Re Driver, whereas the integrated de-emphasis circuitry provides flexibility with signal integrity of the signal after the Re Driver. In addition to providing signal re-conditioning, Peri’s PI2EQX5804C also provides power management Stand-by mode operated by a Power Down pin.
