1. General description
CBTU04083 is an 8-to-4 differential channel multiplexer/demultiplexer switch. The
CBTU04083 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 minimized the
channel-to-channel skew as well as channel-to-channel crosstalk, as required by the
high-speed serial interface. CBTU04083 allows expansion of existing high speed ports for
extremely low power.
