Overview

The TS3USB221ERSER is a high-bandwidth, 1:2 multiplexer/demultiplexer switch designed specifically for switching High-Speed USB 2.0 signals. It features a wide bandwidth of 1.1 GHz which allows signals to pass with minimum edge and phase distortion. The device is optimized for low power consumption and maintains high signal integrity in portable electronic applications.

Why Choose This Part

This switch offers a very low on-state resistance of 6 ohms and a low bit-to-bit skew of 50 ps, ensuring compliant USB 2.0 eye patterns. Its power-off protection feature ensures that the signal paths are high-impedance when VCC is 0V, preventing backflow current into the system.

Applications

Mobile Device Port Expansion
Routing a single USB 2.0 interface between two different physical connectors or internal peripherals in smartphones.
USB Docking Stations
Switching data lines between a local device controller and an external downstream port.
Diagnostic Port Switching
Providing a shared path for USB data and UART or JTAG signals to a common connector for field debugging.

Getting Started

To evaluate this IC, designers can use the TS3USB221EVM evaluation module to verify signal integrity and switching timing. Ensure that traces are impedance-matched to 90 ohms for USB differential pairs and keep the switch as close to the connector as possible to minimize stubs.
