A product Line of Diodes Incorporated PI3PCIE3413A 3.3V, PCI Express 3.0 2-Lane, 3:1 Mux/DeMux Switch, with Power Down Feature Features Description 4 Differential Channel, 3:1 Mux/DeMux e PTh I3PCIE3413A is an 12 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 three locations. Using a unique design Bi-directional operation technique, Diodes Incorporated has been able to minimize the -3dB Bandwidth: 6.8GHz impedance of the switch such that the attenuation observed Low Bit-to-Bit Skew, 10ps max through the switch is mininal. The unique design technique also Low Crosstalk: -40dB 4 GHz oerff s a layout targeted for PCI Express signals, which minimizes Low Insertion Loss: -1.4dB 4 GHz (8.0Gbps) the channel to channel skew as well as channel to channel crosstalk Low Return Loss:-15dB 4GHz (8.0Gbps) as required by the PCI Express specification. Low Off Isolation:-19dB 4GHz (8Gbps) ESD:1.5KV HBM Power Down option Application Supply Voltage 3.3V Routing of PCI Express 3.0, signals with low signal attenuation.
