Overview
The CBTL05023BS,118 is a multiplexer/demultiplexer switch chip designed by NXP USA Inc. for applications involving DisplayPort v1.2 signals and the control signals of a 10 Gbit/s channel. This chip is specifically tailored for Thunderbolt applications, where it manages the switching between different signal paths efficiently. Although the 10 Gbit/s channel does not pass through this switch, the chip provides necessary control signals and DC-biasing pull-down resistors to facilitate an external 10 Gbit/s channel. The CBTL05023BS,118 is no longer in production but remains relevant for existing designs and legacy systems.
