MAX14950A
Single-Lane PCIe Equalizer/Redriver
Ultra-Small Equalizer/Redriver Improves PCIe Signal Integrity Across Systems for Gen 3.0 Applications
|
Status
Active: In Production.
Description
The MAX14950A 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 MAX14950A 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. It is specified over the 0°C to +70°C commercial operating temperature range.
