The CBTL05023 is a multiplexer/demultiplexer switch chip for DisplayPort v1.2 signals
and the control signals of a 10 Gbit/s channel. The 10 Gbit/s channel does not pass
through this switch. This chip provides BIASOUT output control signal, and the
DC-biasing pull-down resistors to facilitate an external 10 Gbit/s channel.
The AUX MUX is a 2 : 1 switch with CA_DETect pin selecting between AUX and DDC
(Direct Display Control) signals.
The DP MUX is a 2 : 1 switch that selects between DPML (DisplayPort Main Link) and
