PART OBSOLETE - USE PI3PCIE3412A A product Line of Diodes Incorporated PI3PCIE3412 3.3V, PCI Express 3.0 2-Lane, 2:1 Mux/DeMux Switch, with Single Enable Features Description 4 Differential Channel, 2:1 Mux/DeMux The PI3PCIE3412 is an 8 to 4 differential channel multiplexer/ demultiplexer switch. This solution can switch 2 full PCI PCI Express 3.0 Performance, 8.0Gbps Express 3.0, lanes to one of two locations. Using a unique design Bi-directional Operation technique, Diodes has been able to minimize the impedance of Low Bit-to-Bit Skew, 10ps max the switch such that the attenuation observed through the switch Low channel-to-channel skew, 20ps max is minimal. The unique design technique also offers a layout Low Crosstalk: -35dB 4 GHz targeted for PCI Express signals, which minimizes the channel to High Off Isolation: -22dB 4 GHz (8.0Gbps) channel skew as well as channel to channel crosstalk as required Low insertion loss: -1.3dB 4 GHz (8.0Gbps) by the PCI Express specification . PI3PCIE3412 can also be used Return loss: -21dB 4 GHz for application up to 12Gbps Support for DP1.2 - HBR2, HBR, RBR Supply Voltage 3.3V Application o o Industrial Temperature Range: -40 C to 85 C Routing of PCI Express 3.0, DP1.2, USB3.0, SAS2.0, SATA3.0, XAUI, RXAUI signals with low signal attenuation.
