概述

Description

PI3USB31ZUAEX is a USB 3.x signal‑integrity device (a redriver/retimer) from Renesas Electronics (formerly Pericom). It sits between a USB host/controller and a USB device to restore and condition high‑speed SuperSpeed signals, helping to extend cable length or compensate for PCB trace losses while meeting USB 3.x timing/spec requirements. Key features typically include signal retiming and equalization, pre-emphasis, built‑in ESD protection, and low power operation. The ZUAEX suffix denotes a specific package/revision and temperature grade; consult the datasheet for exact pinout, supply voltages, and configuration options. Common applications are laptops/desktops, embedded systems, and USB hubs where maintaining signal integrity over longer traces or cables is important.

Features

Here are the typical features of PI3USB31ZUAEX (USB switch/mux):
- 3-port USB data-switch (crossbar) for sharing a USB device/host among multiple ports
- USB 2.0 High-Speed capable (up to 480 Mbps)
- Built-in routing logic to connect any port pair under control
- Easy control interface (enable/select pins) for port switching
- Low on-resistance data path for minimal signal loss
- 5V-tolerant I/Os suitable for USB signaling
- ESD protection on D+ and D− lines
- Overcurrent/short-circuit protection on VBUS
- Low power consumption
- Small package (e.g., 16-pin QFN) with RoHS-compliant “ZUAEX” variant option
- Suitable for USB hubs, docking stations, KVMs, and USB sharing applications
Note: For exact electrical specs, pinout, and operating conditions, please consult the official datasheet.

Package

20-pin QFN package (4x4 mm) with an exposed pad.

Pinout

- Pin count: 16 pins (QFN-16 style)
- Function: USB data-path switch/multiplexer (2:1) for USB 2.0/3.0 signals, routing the differential D+/D− (and SS pairs for USB 3.0 as applicable) between ports under control (with enable) for host/device port selection.

Manufacturer

Manufacturer: Diodes Incorporated (originally Pericom Semiconductor; Pericom assets were acquired by Diodes in 2019).
About the company: Diodes Incorporated is a global semiconductor company that designs and manufactures discrete and integrated circuits, including analog, logic, and high-speed data‑communication ICs used in networking, computing, consumer electronics, automotive, and industrial applications.

Application

PI3USB31ZUAEX is a USB 3.0 (SuperSpeed) 2:1 switch/re-timer for routing and retiming USB signals. Applications include:
- USB 3.0 hubs and docking stations
- Motherboards, notebooks, and front-panel I/O
- USB-C adapters and external storage enclosures
- Systems needing reliable high-speed USB paths over longer cables or multiple connectors

Equivalent

PI3USB31ZUAEX is a dual-channel USB 3.0 redriver/retimer. Comparable devices from other vendors include:
- Renesas HD3SS3200 / HD3SS3201 (dual-channel USB 3.0 redriver)
- Texas Instruments TUSB1002 (USB 3.0 retimer/repeater)
Note: exact pinout, voltage, and package must match your design; there may not be a direct 1:1 drop-in.
