CBTL05023
Overview
The CBTL05023 is a multiplexer/demultiplexer switch chip for DisplayPort v1.2 signals and the control signals of a 10 Gbit/s channel. The 10 Gbit/s channel does not pass through this switch.
- 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 channel:; Low insertion loss: -0.5 dB at 5 MHz; Low return loss: -19 dB at 5 MHz; Low ON-state resistance: 7.5 ; Bandwidth: 5 GHz; Low off-state isolation: -75 dB at 5 MHz; Low crosstalk: -40 dB at 5 MHz; Common-mode input voltage VIC: 0 V to 3.3 V; Differential input voltage VID: 1.4 V (maximum)
- DDC channel has DDC_CLK and DDC_DAT I2C signals; 100 kHz 3.3 V voltage swing
- Both AUXIO+ and AUXIO- outputs have 900 (20 %) pull-down resistor that is enabled by the status of the BIASOUT output pin; These pull-down resistors provide DC bias for the 10 Gbit/s channel NXP Semiconductors
