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.
