NCN2612B
6-Channel Differential 1:2
Switch for PCIe 2.0 and
Display Port 1.1
The NCN2612B is a 6−Channel differential SPDT switch designed
to route PCI Express Gen2 and/or DisplayPort 1.1a signals. Due to the
ultra−low ON−state capacitance (2.1 pF typ) and resistance (8 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
5x11x0.75 mm WQFN56 package. The NCN2612B uses 80% less
quiescent power than other comparable PCIe switches.
