PI2PCIE2212 PCI Express(R) 2.0, 1-Lane, 2:1 Mux/DeMux Switch w/ Single Enable Features Description * * * * * * * * * Pericom Semiconductor's PI2PCIE2212 is a 4 to 2 differential, bi-directional channel multiplexer/demultiplexer switch. Due to its low bit-to-bit skew, high channel-to-channel noise isolation and bandwidth, this product is ideal for PCI Express(R) 2.0 signal switching at 5.0Gbps. 2 Differential Channel, 2:1 Mux/DeMux PCI Express(R) 2.0 performance, 5.0 Gbps Bi-directional operation Low Bit-to-Bit Skew, 7ps Low Crosstalk: -38dB@2.5GHz Low Off Isolation: -25dB@2.5GHz VDD Operating Range: 1.5V to 1.8V 0.1V ESD Tolerance: 2kV Packaging: - 28-contact TQFN (3.5 x 5.5mm) Application Switch a PCI Express(R) lane output between two PCI Express lane inputs Truth Table Function SEL A to B L A to C H 13-0023 1 GND 25 B0+ 2 23 B0- 3 22 B1+ AO+ 4 21 B1- 1 SEL VDD 20 GND 19 VDD 7 18 C0+ VDD 8 17 C0- VDD 9 16 C1+ GND 10 15 C1- AO- 5 A1+ 6 A1- GND 11 12 13 VDD SEL 28 27 26 24 GND 14 GND C0+ C0C1+ C1- VDD VDD B0+ B0B1+ B1- GND VDD A0+ A0A1+ A1- GND Pin Description (Top-Side View) Block Diagram PS8971B 02/08/13 PI2PCIE2212 PCI Express(R) 2.0, 1-Lane 2:1 Mux/DeMux Switch w/ Single Enable Maximum Ratings (Above which useful life may be impaired.
