We are evaluating ADV7612 and have some question with regards to the working .
Board design is as follows
Source Physical cable -> ADV7612 -> Custom board
After Reset till the input signal is applied we find the HSYNC , VSYNC and Enable signal has a Fixed state (High or Low ) Output .
When the Input is connected (Source PHY ) the HSYNC , VSYNC and Enable starts to output , but when the Input is disconnected (Source PHY)
We see that the HSYNC , VSYNC and Enable is not set to Fixed state (High or Low state) instead it is still output HSYNC , VSYNC and Enable signal .
Could you please let me know if there is a register setting that Auto detects no input and Fix the HYSNC , VSYNC and other related signal to either High or Low .
With best regards and wishes
