3 Description

The TS3USB221E 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 (1GHz) 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 TS3USB221E 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 (480Mbps).

The TS3USB221E integrates ESD protection cells on

all pins, is available in a SON package (3mm ×

3mm) as well as in a tiny μQFN package (2mm

× 1.5mm) and is characterized over the free-air

temperature range from –40°C to 85°C.
