I have some questions about TMDS clock output frequency of ADV7511W.
My customer uses ADV7511W on their system.
When HDMI cable is connected to the system, he can see incorrect frequency on the TMDS clock temporarily
while / after the registers are set for the ADV7511W. After a short time, the frequency becomes correct.
I tried this on evaluation board (ADV748x Eval board) with script files.
I can see the same phenomenon when the script is first written.
=>Generally, HDMI cable is connected, then CPU writes the registers of ADV7511.
But S/W driver is not implemented to our ADV748x Eval board, so I confirmed the TMDS waveform when the script is first written.
I described the waveforms and our questions in attached file.
Please see the file "ADV7511W_TMDS_CLK.xlsx".
