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