A product Line of Pb Diodes Incorporated Lead-free Green PI3PCIE2215 3.3V, PCI Express 1-lane, 2:1 Mux/DeMux Switch Features Description 2 Differential Channel, 2:1 Mux/DeMux Diodes PI3PCIE2215 is a 4 to 2 differential channel multiplexer/ demultiplexer switch. e Th PI3PCIE family of switch solutions is fully PCI Express 2.0 Performance, 5.0Gbps compliant with PCIe signals at 5.0Gbps. Due to its low bit-to-bit Pinout optimized for placement between two PCIe slots skew, high channel-to-channel noise isolation and high bandwidth, Bi-directional operation this product is ideal for PCI Express switching. Low Bit-to-Bit Skew, 5ps max Low Crosstalk: -26dB 5 GHz Low Off Isolation: -20dB 5 GHz Application VDD Operating Range: +3.3V Switch a PCI Express lane output between two PCI Express lane ESD Tolerance: 2kV HBM inputs Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. Green Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative.
