NCN2411
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 W 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.
