DESCRIPTION
The TS3USB221A is a high-bandwidth switch
specially designed for the switching of high-speed
USB 2.0 signals in handset and consumer
applications, such as cell phones, digital cameras,
and notebooks with hubs or controllers with limited
USB I/Os. The wide bandwidth (900 MHz) of this
switch allows signals to pass with minimum edge and
phase distortion. The device multiplexes differential
outputs from a USB host device to one of two
corresponding outputs. The switch is bidirectional and
offers little or no attenuation of the high-speed signals
at the outputs. It is designed for low bit-to-bit skew
and high channel-to-channel noise isolation, and is
compatible with various standards, such as
high-speed USB 2.0 (480 Mbps).
The TS3USB221A integrates ESD protection cells on
all pins, is available in a tiny µQFN package (2.0 mm
× 1.5 mm) and is charaterized over the free air
temperature range from –40°C to 85°C.
