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) 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). • 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 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. • 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 Block Diagram Pin Description D+ DSEL OE M- 10 9 8 Y+ 1 7 D+ Y- 2 6 D- 3 4 5 M+ Y- VDD M+ M- Y+ SEL OE SEL OE Y+ Y- X H Hi-Z Hi-Z L L M+ M- H L D+ D- All trademarks are property of their respective owners. 14-0215 GND Truth Table 1 www.pericom.com12/18/14 PI3USB103 USB 2.0 High-Speed (480 Mbps) Signal Switch with Vbus Short Protection Maximum Ratings (Above which useful life may be impaired.

Guaranteed 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 0.25ns for 10pF 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 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.
