My customer is using TDP158 on their notebook project, on source side. And they only need to support HDMI 1.4b. Here is the questions:
1. If they use DDC Snoop mode, the SDA/SCL_SNK was connected to the DDC too, they are asking what is the purpose for connecting these two pins under HDMI 1.4b, for data rate detection?
2. In special mode, the data rate was fixed on 5.4Gbps, they are asking if under HDMI 1.4b, will it has any problem on the signal condition? Any suggestion on special mode under 1.4b?
