CBTL05024 Overview
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. 1 switch that selects between Thunderbolt data path and DisplayPort v1.2 side-band signals either DDC or AUX.
CBTL05024 Key Features
- 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 AU
- When CA_DET is HIGH, DDC path is selected
- Differential TB channel
- Low insertion loss: 1.3 dB at 5 GHz
- Low return loss: < 20 dB at 5 GHz
- Low ON-state resistance: 8
- Bandwidth: 10 GHz
- Low off-state isolation: 20 dB at 5 GHz
