PI3USB103
USB 2.0 High-Speed (480 Mbps) Signal Switch with Vbus Short Protection
Features
Description
USB 2.0 compliant (high speed and full speed)
RON is 3.0Ω typical @ VDD = 3.0V
Low bit-to-bit skew
e PI3USB103 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. e device multiplexes
differential outputs from a USB Host device to one of two cor-
responding outputs. e 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).
Low Crosstalk: –33dB @ 480 Mbps
Off Isolation: –30dB @ 480 Mbps
Near-Zero propagation delay: 250ps
Channel On Capacitance: 6.0pF (typ)
VDD Operating Range: 2.7V to 4.4V
e PI3USB103 offers over voltage protection per the USB 2.0
specification. With the chip powered on or off, all I/O pins can
withstand a short to Vbus. If VDD = 0V, the I/Os can still have
Data pin I/O ESD (pins 1, 2, 4, 5, 6, and 7): 4kV contact
per IEC61000-4-2 spec
-0.5dB BW of 400MHz
signals present, and the signal will NOT leak through to VDD
.
I/O pins have over-voltage protection and can tolerate a
short to Vbus
