Design Requirement

The TDP142 can be designed into many types of applications. All applications have certain requirements for the system to work properly. For example, source application uses different hardware configuration on the HPD channel and AUX channel from a sink application. The device can be configured by using I2C. However, the GPIO configuration is provided as I2C is not available in all cases. Additionally, because sources may have different naming conventions, please confirm the link between source and receptacle is correctly mapped through the TDP142.
