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-tobit
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.
