(ADV7611)Why ADV7611 output SCLK befor HDMI input?

Q1) Why ADV7611 output this frequency?

       There is a way to limit on the MCLK on our HDMI receivers: I believe, this might solve SCLK from ADV7611 issue also. Let us check and update you.

        Please refer this thread ez.analog.com/.../how-do-we-limit-the-mclk-output-frequency-on-the-hdmi-receivers

Q2) Is the frequency always constant at 9.8437 MHz?

         No,The SCLK frequency is 64 times the LR (sample clock).

Thanks,

Hi !

We will wait your update.

Our point is when user set up ADV7611 even if their is no HDMI input, what is the value for SCLK frequency.

We want know because our customer want to reduce EMI.

So it will be useful if you can tell how to limit ADV7611 SCLK frequency but still we want to know the initial SCLK frequrncy.

Also I understood that SCLK is 64 times the LR.

Then we want to know LR sample clock initial frequency.

Anyway we will wait your advice

Best regards
