DESCRIPTION

· CBTL02043A/B is a 2 differential channel, 2-to-1 multiplexer/demultiplexer switch designed for USB 3.1, PCI Express Gen 3, and other high-speed serial interfaces.

· It features minimized impedance, low attenuation, and reduced channel-to-channel skew and crosstalk.

· CBTL02043A has input and output pins on opposite sides, suitable for edge connectors on motherboards.

· CBTL02043B has outputs on both sides, ideal for placement between connectors to multiplex differential signals.
