General description

CBTL06DP212 is a high performance multi-channel Generation 2 multiplexer meant for

DisplayPort (DP) v1.2, v1.1a or Embedded DisplayPort applications operating at data rate

of 1.62 Gbit/s, 2.7 Gbit/s or 5.4 Gbit/s. It is designed using NXP proprietary

high-bandwidth pass-gate technology and it can be used for 1 : 2 switching or 2 : 1

multiplexing of four high-speed differential AC-coupled DP channels. Further, it is capable

of switching/multiplexing of Hot Plug Detect (HPD) signal as well as Auxiliary (AUX) and

Display Data Channel (DDC) signals. In order to support GPUs/CPUs that have dedicated

AUX and DDC I/Os, CBTL06DP212 provides an additional level of multiplexing of AUX

and DDC signals delivering true flexibility and choice.

A typical application of CBTL06DP212 is on motherboards where one of two GPU

DisplayPort sources needs to be selected to connect to a DisplayPort sink device or

connector. A controller chip selects which path to use by setting a select signal HIGH or

LOW. Due to the bidirectional nature of the signal paths, CBTL06DP212 can also be used

in the reverse topology, e.g., to connect one display source device to one of two display

sink devices or connectors.
