CBTL05024
description
The CBTL05024 is a multiplexer/demultiplexer switch chip optimized to interface the Thunderbolt/Mini DP connector with Thunderbolt systems. It supports 10.3125 Gbit/s Thunderbolt or Display Port v1.2 channels.
The TB MUX is a 3 : 1 switch that selects between Thunderbolt data path and Display Port v1.2 side-band signals
- either DDC or AUX.
The DP MUX is a 2 : 1 switch that selects between DP ML (Display Port 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.
2. Features and benefits
2.1 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...
