A product Line of Diodes Incorporated PI3PCIE3412A 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 e PTh I3PCIE3412A is an 8 to 4 differential channel multiplexer/ demultiplexer switch. This solution can switch 2 full PCI Express PCI Express 3.0 Performance, 8.0Gbps 3.0, lanes to one of two locations. Using a unique design Bi-directional Operation technique, Diodes Incorporated has been able to minimize the Low Bit-to-Bit Skew, 10ps max impedance of the switch such that the attenuation observed Low channel-to-channel skew, 20ps max through the switch is minimal. The unique design technique Low Crosstalk: -35dB 4 GHz also oerff s a layout targeted for PCI Express signals, which High Off Isolation: -22dB 4 GHz (8.0Gbps) minimizes the channel to channel skew as well as channel to Low insertion loss: -1.3dB 4 GHz (8.0Gbps) channel crosstalk as required by the PCI Express specification. Return loss: -21dB 4 GHz e PTh I3PCIE3412A can also be used for application up to 12Gbps. ESD:1.5KV HBM Support for DP1.2 - HBR2, HBR, RBR Application Supply Voltage 3.3V o o Routing of PCI Express 3.0, DP1.2, USB3.0, SAS2.0, SATA3.0, XAUI, Industrial Temperature Range: -40 C to 85 C RXAUI signals with low signal attenuation.
