USB 2.0 High-Speed (480 Mbps) Signal Switch

Description
The PI3USB102 is a single differential channel 2:1 multiplexer/de-
multiplexer USB 2.0 Switch. Industry leading advantages include a
propagation delay of less than 250ps, resulting from its low channel
resistance and I/O capacitance. 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, high channel-to-channel noise isolation and is compatible
with various standards, such as High Speed USB 2.0 (480 Mb/s).
The PI3USB102 offers over voltage protection per the USB 2.0
specifi cation. With the chip powered on or off, all I/O pins can
withstand a short to Vbus (5V +/-10%). This feature can only be
offered if a 100-ohm pull up resistor is placed between V
to the power supply.
In situations where Vbus can be as high as 7V, Pericom recommends
changing the resistor value from 100ohm to 200ohm. Pericom can
still support over-voltage protection up to 7V, as long as the 200ohm
resistor is present.
