Description

The MAX14975 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 optimal layout and minimal space requirements. The device is specified over the -40°C to +85°C extended operating temperature range.
