PI3USB10LP-A USB 2.0 High-Speed (480 Mbps) Signal Switch Targeted for Battery Powered Applications Features Description • USB 2.0 compliant (high speed and full speed) The PI3USB10LP-A 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 5.5Ω typical @ VCC = 3.0V • Low bit-to-bit skew • Low Crosstalk: –40dB @ 500 Mbps • Off Isolation: –35dB @ 500 Mbps • Near-Zero propagation delay: 250ps • Switching speed: 9ns • Channel On Capacitance: 5.5pF The PI3USB10LP-A offers overvoltage protection per the USB 2.0 specification. 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 VCC pin to the power supply. • VCC Operating Range: 2.7V to 4.2V ±10% • Data pin I/O ESD: 12kV HBM protection per JESD22-A114D specification • 1,000 MHz Bandwidth • I/O pins have over-voltage protection and can tolerate a short to Vbus • Packaging (Pb-free & Green): • 10-contact UQFN (ZM10) (1.4x1.8) • 10-contact TQFN (ZL10) (1.3X1.6) Application • Routes signals for USB 2.0 • Hand-held devices Pin Description (Top View) Block Diagram D- D-A OE D+A VCC D+ SEL OE 10 9 8 D+B D-B SEL Function H X I/O's = Hi-Z L L D(+/-) to D(+/-)A L H D(+/-) to D(+/-)B 07-0096 1 D-A D+B 2 6 D-B 3 4 5 D- SEL 7 G ND OE 1 D+ Truth Table D+A PS8858G 05/02/07 PI3USB10LP-A USB 2.0 High-Speed (480 Mbps) Signal Switch Targeted for Battery Powered Applications Maximum Ratings (Above which useful life may be impaired.

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. 07-0096 3 PS8858G 05/02/07 PI3USB10LP-A USB 2.0 High-Speed (480 Mbps) Signal Switch Targeted for Battery Powered Applications Test Circuit for Dynamic Electrical Characteristics HP4396B R1 S1 T1 PI3USB10LP-A HP11667A 50-ohm Test Circuit for Electrical Characteristics 6.0V VCC 200-ohm Pulse Generator VIN D.U.T VOUT 10pF CL RT 200-ohm Notes: CL = Load capacitance: includes jig and probe capacitance.
