PI3USB221
High-Speed USB2.0 1:2 Multiplexer/
DeMultiplexer Switch with Signal Enable
Description
The PI3USB221 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 (1.1 GHz) 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).

Notes:
1. For Max or Min conditions, use the appropriate value specified under Electrical Characteristics for the applicable device type.
2. Specified by design
3. The switch contributes no propagational delay other than the RC delay of the on resistance of the switch and the load capacitance. The time
constant for the switch alone is of the order of 0.25 ns for 10-pF load. Since this time constant is much smaller than the rise/fall times of typical
driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch, when used in a system, is determined
by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.
