General description
The CBTL05024 is a multiplexer/demultiplexer switch chip optimized to interface the Thunderbolt/MiniDP connector with Thunderbolt systems.
It supports 10.
3125 Gbit/s Thunderbolt or DisplayPort v1.
2 channels.
The TB MUX is a 3 : 1 switch that selects between Thunderbolt data path and DisplayPort v1.
2 side-band signals — either DDC or AUX.
The DP MUX is a 2 : 1 switch that selects between DP ML (DisplayPort Main Link) and LS TX/RX signals.
Both LSTX and LSRX are the side-band signals for Thunderbolt channel.
This chip also includes HPD and CA_DET buffers for HPD_IN and CA_DET control signals.
CBTL05024 is powered by a 3.
3 V supply and it is available in a 3 mm 3 mm HVQFN24 package with 0.
4 mm pitch.

1 TB MUX 3 : 1 switch
This 3 : 1 switch is implemented by two cascaded 2 : 1 switches The first 2 : 1 10G MUX is controlled by TB_ENA, AUXIO_EN and DP_PD pins The second 2 : 1 AUX MUX is controlled by CA_DET signal multiplexing of the 720 Mbit/s Differential FAUX (or 1 Mbit/s AUX) and DDC (Direct Display Control) signals When CA_DET is HIGH, DDC path is selected
