TITS3USB221
Overview
The TS3USB221 is a high-bandwidth, bidirectional 2:1 switch designed for multiplexing high-speed USB 2.0 signals at 480Mbps. It features a 1GHz bandwidth to maintain signal integrity and includes 1.8V compatible control inputs for seamless integration with low-voltage mobile processors. The device is optimized for power-sensitive applications with a low shutdown current of 1uA.
Why Choose This Part
The 1GHz typical bandwidth ensures minimal edge distortion for high-speed data while the low bit-to-bit skew prevents timing errors. It offers high channel-to-channel noise isolation and supports a wide supply range of 2.3V to 3.6V, making it versatile for battery-powered designs. Additionally, the I/O pins are 5V tolerant, providing protection when connected to external USB ports.
Applications
Key Specifications
Getting Started
For evaluation, utilize the TS3USB221EVM to test signal integrity and switching performance. Ensure that PCB traces are matched to 90-ohm differential impedance and place the switch as close as possible to the USB connector to minimize stubs. Control logic is simple, using the OE (Output Enable) and S (Select) pins to manage signal routing.
