4-Channel Differential 1:2 Mux/Demux Switch for PCI Express Gen2

The NCN2411 is a 4−Channel differential SPDT switch designed to route PCI Express Gen2 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), this switch is ideal for switching high frequency signals up to a signal bit rate (BR) of 5 Gbps. This switch pinout is designed to be used in BTX form factor desktop PCs and is available in a space−saving 3.5x9x0.75 mm WQFN42 package.
