PI3USB102E
USB 2.0 High-Speed (480 Mbps) Switch with 5V Protection
The PI3USB102E is a single differential channel 2:1 multiplexer/
demultiplexer USB 2.0 Switch. Industry leading advantages include a
propagation delay of 250ps, resulting from its low channel resistance
and I/O capacitance. PI3USB102E is bidirectional and offers very
little attenuation of high-speed signals. 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 PI3USB102E offers over voltage protection for the Y+/Y- pins
as per the USB 2.0 specification. With the chip powered on or off
if Y+/Y- pins are shorted to VBUS (5V +/- 5%), M+/M- and
D+/D- outputs are clamped to provide voltage protection for
downstream devices.
