概述

Description

PI3USB31532ZLEX is a USB data-path switch/multiplexer from the PI3USB family (Diodes Incorporated/ Pericom). It is used to route USB differential data lines between ports (upstream host and downstream devices) and supports port switching in USB designs such as docks, hubs, or Type-C port implementations.
Key points:
- Provides controlled crosspoint for USB 2.0 (Hi-Speed) and USB 3.x (SuperSpeed) data paths.
- Low on-resistance data path, designed for high-speed signaling.
- Integrated ESD protection and desired I/O tolerance (5V tolerant on many pins).
- Control interface options typically include GPIO or SMBus/I2C variants, depending on the exact device.
- ZLEX suffix refers to the specific package/lead-free/ RoHS-compliant option.
Applications include USB-C port controllers, docking stations, USB hubs, and devices requiring flexible USB port routing or role-switching. For exact features, pinout, voltage ranges, and timing, consult the official PI3USB31532ZLEX datasheet.

Features

Here are the typical features of the PI3USB31532ZLEX (USB 3.0 switch/mux):
- 2:1 USB 3.0 (SuperSpeed) crosspoint switch to route one upstream port to two downstream ports (or vice versa)
- Supports USB 3.0 data rate up to 5 Gbps; backward compatibility with USB 2.0/1.1
- Single enable/control input to select the active path
- Low insertion loss and low skew for high‑speed signaling
- Hot‑swap/power‑on sequencing support
- ESD protection on USB data lines
- 3.3V logic compatibility (I/O operated at logic levels suitable for standard USB controllers)
- RoHS-compliant, lead‑free (ZLEX package)
- Industrial temperature range (typical -40°C to 85°C)
- Suitable for use in docking stations, hubs, USB switches, and port‑multiplexing apps
Note: Always verify exact electrical specs and package details from the latest datasheet for the ZLEX variant.

Package

PI3USB31532ZLEX comes in a 16‑pin QFN package (3x3 mm) with an exposed pad (EP).

Pinout

Pin count: 20 pins (QFN package).
Function: USB 3.0 switch/multiplexer (port switch) that routes SuperSpeed TX/RX pairs and USB 2.0 D+/D− signals between a host controller and one of two downstream USB ports.

Manufacturer

Manufacturer: Renesas Electronics Corporation (originally Pericom Semiconductor).
What kind of company: A Japanese multinational semiconductor company that designs and manufactures high-speed interconnect ICs (USB, PCIe, HDMI), as well as analog, power management, and microcontroller products.

Application

PI3USB31532ZLEX is a USB 3.x high‑speed signal‑integrity device (retimer/redriver and switch). Common applications:
- Re-timing/re-driving USB 3.x signals on long PCB traces or through connectors
- USB hubs, docking stations, and port expanders
- USB‑C adapters and Type‑C docks (USB‑A dongles/cables)
- Motherboards, notebooks, tablets, and embedded/industrial equipment needing robust USB links
- External USB add‑on cards and controllers
