ADV7611, MCLKOUT just after starting up

Hi,

 

In regard to ADV7611 as shown in Figure 12(Audio Processor Block Diagram) of UG-180, MCLKOUT is made from MCLK_FS_N setting, TMDS clock, and "CTS" & "N" values of ACR packet data.

If there is no ACR packet data, for example, just after starting up ADV7611 and before having HDMI input data, how is the frequency of MCLKOUT decided ?

 

We are observing specific frequency of MCLKOUT just after start and before input data and would like to know whether it can change or not.

 

Your support would be always appreciated.

 

Best Regards,
