General Description

The MAX14972 dual SuperSpeed USB 3.0 equalizer/

redriver utilizes programmable input equalization and

output deemphasis to reduce deterministic jitter and

restore signal loss caused by circuit-board or signal-

cable losses, and allows optimal placement of key

SuperSpeed USB 3.0 components and longer circuit-

board traces or cables. The device features advanced

power management with receiver detection and explicit

support for USB 3.0 low-frequency periodic signals

(LFPS).

The device is available in a small, 24-pin (4.0mm x

4.0mm) TQFN package with flow-through traces for opti-

mal layout and minimal space requirements. The device

is specified over the 0NC to +70NC commercial operating

temperature range.
