MAX14955 - Single-Lane PCIe Gen III Redriver

Description

The MAX14955 dual equalizer/redriver improves PCI Express® (PCIe) signal integrity by providing programmable input equalization.

This feature reduces deterministic jitter and redrives circuitry to reestablish deemphasis, which compensates for circuit-board loss at high frequencies.

Features

  • electrical idle and receiver detection. The MAX14955 is available in a small, 40-pin, 5.0mm x 5.0mm TQFN package with flow-through traces for optimal layout and minimal space requirements. The device is specified over the -40°C to +85°C extending operating temperature range.

MAX14955 Single-Lane PCIe Gen III Redriver with Equalization and Extended Temperature Operation General Description The MAX14955 dual equalizer/redriver improves PCI Express® (PCIe) signal integrity by providing programmable input equalization. This feature reduces deterministic jitter and redrives circuitry to reestablish deemphasis, which compensates for circuit-board loss at high frequencies. The device permits optimal placement of key PCIe components and allows for longer runs of stripline, microstrip, or cable. The device contains two identical channels capable of equalizing PCIe Gen III (8GT/s), Gen II (5GT/s), and Gen I (2.5GT/s) signals and features electrical idle and receiver detection. The MAX14955 is available in a small, 40-pin, 5.0mm x 5.
