EVALUATION KIT AVAILABLE
MAX14972
Dual SuperSpeed USB 3.0 Equalizer/Redriver
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.
