PI3USB302 3.3V, USB 3.0, 1-Port, 2:1 Mux/DeMux Switch Features Description ÎÎ2 Differential Channel, 2:1 Mux/DeMux Pericom Semiconductor’s PI3USB302 is a 2-differential channel bi-directional multiplexer/demultiplexer switch. Due to its low bit-to-bit skew, high channel-to-channel noise isolation and bandwidth, this product is ideal for USB 3.0 signal switching at 5.0 Gbps. ÎÎUSB 3.0 SuperSpeed switch ÎÎBi-directional operation ÎÎLow Bit-to-Bit Skew, 10 ps max ÎÎLow channel-to-channel skew: 20 ps max ÎÎLow insertion loss: 1 dB @ 2.5 GHz (5.0 Gbps) Application ÎÎLow Crosstalk: 33 dB @ 2.5 GHz (5.0 Gbps) Routing USB 3.0 SuperSpeed signals ÎÎLow Off Isolation: 27 dB @ 2.5 GHz (5.0 Gbps) ÎÎVDD Operating Range: 3.3 V +/-10% ÎÎESD Tolerance: 1 kV ÎÎPackaging (Pb-free & Green): àà – 20-contact TQFN (2.5 × 4.5mm) Block Diagram Pin Description (Top-side view) Tx+ TxRx+ Rx- Rx+2 Rx-2 SEL PD Switch Control PD 2 Tx+ TxGND 5 VDD 6 Rx+ 7 RxSEL 1 20 19 Tx1+ 3 18 Tx1- 4 17 Rx1+ 16 Rx1- 15 Tx2+ 14 Tx2- 8 13 Rx2+ 9 12 Rx2- GND 10 Function SEL PD port 1 is active L L port 2 is active H L Both Ports Hi-z, IC power down x H 13-0002 VDD Truth Table 1 11 GND Tx+2 Tx-2 GND Rx+1 Rx-1 VDD Tx+1 Tx1- 12/19/12 PI3USB302 3.3V, USB 3.0, 1-Port, 2:1 Mux/DeMux Switch Pin Description Pin # Pin Name I/O Description 2 PD I Power Down input. see truth table on page 1 for functionality 3 Tx+ I/O 4 Tx- I/O 7 Rx+ 8 Rx- 9 SEL 14 Tx2- 15 Tx2+ 12 Rx2- I/O 13 Rx2+ I/O 17 Rx1+ 16 Rx1- 19 Tx1+ 18 Tx1- 6, 10, 1 5, 11, 20, center pad 13-0002 Signal I/O, Transmit differential pair from common port I/O Signal I/O, Receive differential pair from common port I Operation mode Select (when SEL=0: port 1 is active, when SEL=1: port 2 is active I/O Signal I/O, Transmit differential pair, port 2 Signal I/O, Receive differential pair, port 2 I/O Signal I/O, Receive differential pair, port 1 I/O Signal I/O, Transmit differential pair, port 1 VDD Pwr 3.3V ±10% Positive Supply Voltage GND Pwr Power ground 2 12/19/12 PI3USB302 3.3V, USB 3.0, 1-Port, 2:1 Mux/DeMux Switch Maximum Ratings (Above which useful life may be impaired.
