4-Differential Channel 1:2 Mux/Demux Switch for PCI Express Gen3

The NCN3411 is a 4−Channel differential SPDT switch designed to route PCI Express Gen3 signals. When used in a PCI Express application, the switch can handle up to two PCIe lanes. Due to the ultra−low ON−state capacitance (2 pF typ) and resistance (7.5  typ), these switches are ideal for switching high frequency data signals up to a signal bit rate of 8 Gbps. This switch pinout is designed to be used in BTX form factor desktop PCs and is available in a space−saving 3.5 x 9 x 0.75 mm WQFN42 package.
