Introduction
The TS3USB221/A/E EVM is an evaluation module for the Texas Instruments (TI) 1:2
multiplexer/demultiplexer high-bandwidth USB switches. It is specially designed for high-speed USB 2.0
signals, supports bidirectional signaling, and offers high-bandwidth (1.1 GHz). When interfacing other USB
devices with this EVM, the switch allows signals to pass with minimum edge and phase distortion as well
as little or no signal attenuation.
This evaluation module is designed to demonstrate the small printed circuit board (PCB) areas that can be
achieved when designing with the TS3USB221/A/E USB switches. It is powered from the 5-V rail of the
USB input. Additionally, the TS3USB221/A/E provides an output enable input and an output select input
for flexible configuration of the USB. See
for the EVM block diagram.
