PI3PCIE2215 3.3V, PCI Express(R) 1-lane, 2:1 Mux/DeMux Switch Features Description * 2 Differential Channel, 2:1 Mux/DeMux Pericom Semiconductor's PI3PCIE2215 is a 4 to 2 differential channel multiplexer/demultiplexer switch. The PI3PCIE family of switch solutions is fully compliant with PCIe(R) signals at 5.0Gbps. Due to its low bit-to-bit skew, high channel-to-channel noise isolation and high bandwidth, this product is ideal for PCI Express switching. PCI Express(R) 2.0 Performance, 5.0Gbps Pinout optimized for placement between two PCIe slots Bi-directional operation Low Bit-to-Bit Skew, 5ps max Low Crosstalk: -26dB@5 GHz Low Off Isolation: -20dB@5 GHz VDD Operating Range: +3.3V ESD Tolerance: 2kV HBM Packaging (Pb-free & Green): - 28 contact TQFN (ZH) Application Switch a PCI Express(R) lane output between two PCI Express lane inputs AI+ AIBI+ BI- AOa+ AOaBOa+ BOaAOb+ AObBOb+ BOb- SEL Function SEL xIy to xOay L xIy to xOby H 09-0033 1 AI- 28 27 26 1 25 24 GND 2 23 AOa+ AOb+ 3 22 AOa- AOb- 4 21 GND BI+ 5 20 VDD BI- 6 19 BOa+ BOb+ 7 18 BOa- BOb- 8 17 VDD VDD 9 16 SE L NC 10 15 GND GND 11 12 13 GND VDD Truth Table AI+ GND VDD Pin Description (Top-side view) GND VDD Block Diagram 14 GND VDD * * * * * * * * * PS9069 08/03/09 PI3PCIE2215 3.3V, PCI Express(R), 1-Lane, 2:1 Mux/DeMux Switch Signal Descriptions 1 2 Pin Number Pin Name AI+ AI- Type Differential input 23 22 AOa+ AOa- Differential pass-through input 3 4 AOb+ AOb- Differential pass-through input 5 6 BI+ BI- Differential input 19 18 BOa+ BOa- Differential pass-through input 7 8 BOb+ BOb- Differential pass-through input 11, 13, 15, 21, 24, GND 26, 28, (center pad) 10 NC 16 SEL 9, 12, 14, 17, 20, 25, 27 09-0033 VDD Ground input 3.6V tolerant low-voltage single-ended input Power supply 2 Description Differential input pair from PCIE signal source.
