Description

Request Full Data Sheet

The MAX4950A dual PCI Express® (PCIe) equalizer/redriver operates from a single +3.3V supply. This device improves signal integrity at the receiver through programmable input equalization and redrive circuitry with output deemphasis to correct for high-frequency losses. This device permits optimal placement of key PCIe components and longer runs of stripline, microstrip, or cable.

The MAX4950A contains two identical channels capable of equalizing PCIe Gen I (2.5GT/s) and Gen II (5.0GT/s) signals. The MAX4950A features electrical idle and receiver detection on each channel and a power-saving mode.

The MAX4950A is available in a small 36-pin (6.0mm x 6.0mm) TQFN package with flowthrough traces for optimal layout and minimal space requirements. The MAX4950A is specified over the 0°C to +70°C commercial operating temperature range.
