3 Description
The TS3USB221A device 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. The device also has a low power
mode that will reduce the power consumtion to 1 μA
for portible applications with a battery or limited
power budget. The device 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 device integrates ESD protection
cells on all pins, is available in a tiny μQFN package
(2 mm × 1.5 mm) and is characterized over the free
air temperature range from –40°C to 85°C.
