CBTL05023
description
The CBTL05023 is a multiplexer/demultiplexer switch chip for Display Port 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 (Display Port Main Link) and LSTX/LSRX signals.
This chip also includes three control signal buffers: HPDOUT, CA_DETOUT and BIASOUT.
CBTL05023 is powered by a 3.3 V supply and it is available in 3 mm 3 mm HVQFN24 package with 0.4 mm pitch.
2. Features and benefits
2.1 AUX MUX 2 : 1 switch
- This 2 : 1 switch is controlled by CA_DET signal multiplexing of the 1 Mbit/s differential AUX and DDC (Direct Display Control) signals
- When CA_DET is HIGH, DDC path is selected
- Differential AUX...
