PI3USB103
USB 2.0 High-Speed (480 Mbps) Signal Switch
with Vbus Short Protection
Features
• USB 2.0 compliant (high speed and full speed)
RON is 3.0Ω typical @ VDD = 3.0V
• Low bit-to-bit skew
• Low Crosstalk: –33dB @ 480 Mbps
• Off Isolation: –30dB @ 480 Mbps
• Near-Zero propagation delay: 250ps
• Channel On Capacitance: 6.0pF (typ)
• VDD Operating Range: 3.0V to 3.6V
• Data pin I/O ESD (pins 1, 2, 4, 5, 6, and 7): ±4kV contact per
IEC61000-4-2 spec
• -3dB BW of 1400MHz
• I/O pins have over-voltage protection and can tolerate a short
to Vbus
• Packaging (Pb-free & Green):
− 10-contact TQFN, 1.3mm x 1.6mm x 0.75mm (ZL10)
Application
• Routes signals for USB 2.0
• Hand-held devices
Description
The PI3USB103 is a single differential channel 2:1 multiplexer/
demultiplexer 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 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
signals present, and the signal will NOT leak through to VDD.
