Overview

The PI3USB30532 is a 6x4 differential matrix switch designed to route high-speed signals between a system-on-chip (SoC) and a USB Type-C connector. It supports the simultaneous multiplexing of USB 3.0 at 5Gbps and DisplayPort 1.2 at 5.4Gbps, including integrated switching for the AUX and SBU channels.

Why Choose This Part

This switch offers a high 6GHz bandwidth and low insertion loss of -1.2dB at 5Gbps, ensuring signal integrity for SuperSpeed data and 4K video. It provides design flexibility by allowing configuration through either hardware pin control or a standard I2C interface.

Applications

USB Type-C Docking Stations
Manages the complex signal routing required to switch between USB 3.0 data and DisplayPort Alt Mode video output over a single connector.
Mobile Device Motherboards
Provides a compact solution for smartphones and tablets to output high-definition video to external monitors while maintaining SuperSpeed data links.
Integrated Monitors
Acts as the primary interface switch in displays that utilize USB-C as a combined power, data, and video input.
Ultrabooks and 2-in-1 PCs
Enables thin-and-light laptop designs to support versatile peripheral connectivity through a minimized port count.

Getting Started

When designing with this component, ensure that high-speed differential pairs are impedance-matched to 90 ohms for USB and 100 ohms for DisplayPort. The device requires a supply voltage between 3V and 3.6V and should be placed as close to the USB-C connector as possible to minimize trace attenuation. Configuration is typically handled by a PD (Power Delivery) controller via the I2C bus to manage the transition between data and video modes.
