PI2EQX4402

PI2EQX4402 2.5Gbps x2 Lane Serial PCI Express Repeater/Equalizer Features Two High Speed PCI Express lanes Supports PCI Express data rates (2.5 Gbps) on each lane Adjustable Transmiter De-Emphasis & Amplitude Adjustable Receiver Equalization Two Spread Spectrum Reference Clock Buffer Outputs 100Ω Differential CML I/O’s Low Power (100mW per Channel) Standby Mode – Power Down State VDD Operating Range: 1.8V +/-0.1V Packaging (Pb-free & Green): - 84-ball LFBGA Description Pericom Semiconductor’s PI2EQX4402 is a low power, PCI Express compliant signal re-driver. The device provides programmable equalization, amplification, and de-emphasis by using 7 select bits, SEL[0:6], to optimize performance over a variety of physical mediums by reducing Inter-symbol interference. PI2EQX4402 supports four 100 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. In addition to providing signal re-conditioning, Pericom’s PI2EQX4402 also provides power management Stand-by mode operated by a Bus Enable pin. www.DataSheet4U.com Block Diagram Pin Description (Top View) � � �� � �� � ������ � � �...
