PI3USB2117 Wide Bandwidth, 2-Channel, SPST USB 2.0 Switch w/ ESD and Overvoltage protection Features Description • USB 2.0 compliant The PI3USB2117 is a single differential channel 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 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 • Low bit-to-bit skew • Low Crosstalk: –40dB @ 500 Mbps • I/O pins have over voltage protection and can tolerate a short to Vbus In addition to isolating D+/D- pins from a USB connetor, Pericom's PI3USB2117 solution provides Electrostatic Discharge (ESD) protection, up to 12kV per the JESD22-A114D specification. PI3USB2117 also offers overvoltage protection, per the USB 2.0 specification. With the chip powered on or off, all I/O pins can withstand a direct short to the Vbus pin on the USB connector. In order to enable the overvoltage protection feature, the user must add a 100ohm resistor between the power rail and Vdd pin on the chip, pin 9. • Near-Zero propagation delay: 250ps • Switching speed: 9ns • Channel On Capacitance: 7pF • VDD Operating Range: 2.7V to 4.2V ±10% • Data pin I/O ESD: 12kV HBM protection per the JESD22A114D specification. • -3dB Bandwidth: 1300 MHz (Typ) • Packaging (Pb-free & Green): 10-contact TQFN (ZL10) Application • Routes signals for USB 2.0 • Hand held devices Block Diagram Pin Description 2B 2A Function H X I/O's = Hi-Z L L xA = xB L H Disconnect 8 2B 1 7 OE NC 2 6 1B 3 4 5 2S xS 9 GND OE 10 2A Truth Table 1A CTRL VDD 1S 2S OE 1S 1B 1A Notes: 1. x = 0, 1 07-0238 1 PS8920A 10/26/07 PI3USB2117 Wide Bandwidth, 2-Channel, SPST USB 2.0 Switch w/ ESD and Overvoltage protection Maximum Ratings (Above which useful life may be impaired.

For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. 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. 07-0238 3 PS8920A 10/26/07 PI3USB2117 Wide Bandwidth, 2-Channel, SPST USB 2.0 Switch w/ ESD and Overvoltage protection Test Circuit for Dynamic Electrical Characteristics HP396B S1 R1 T1 PI3USB2117 HP11667A Test Circuit for Electrical Characteristics 1 VDD VOUT Pulse Generator DUT RT 50 7 Test Circuit for Electrical Characteristics 2 2 x VDD VDD 200-ohm Pulse Generator VIN D.U.T VOUT 10pF CL RT 200-ohm Notes: CL = Load capacitance: includes jig and probe capacitance.
