MAX14972

Dual SuperSpeed USB 3.0 Equalizer/Redriver

General Description

Benefits and Features

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).

S Innovative Design Eliminates Need for Costly

External Components

Single +3.3V Supply Operation

S Advanced Power Management for Maximum

Efficiency

1mW (typ) in Standby State

23mW (typ) in Receiver Detect State

82.5mW (typ) in Dynamic Power-Down State

304mW (typ) in Active State

S High Level of Integration for Performance

Very Low Latency with 250ps (typ) Propagation

Delay

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.

10dB (typ) Input/Output Return Loss Up to 2.5GHz

Three-Level Programmable Input Equalization

Six-Level Programmable Output Deemphasis

Explicit LFPS Support with Frequency Shaping

SuperSpeed USB 3.0-Compliant Receiver

Detection

Low-Voltage (1.8V) Compatible Controls

Excellent Jitter and Loss Compensation Capability
