General description

CBTU04082 is an 8-to-4 differential channel multiplexer/ demultiplexer switch. The

CBTU04082 can switch four differential signals to one of two locations. Using a unique

design technique, NXP has minimized the impedance of the switch such that the

attenuation observed through the switch is negligible, and also minimizes the

channel-to-channel skew as well as channel-to-channel crosstalk, as required by the

high-speed serial interface.
