Hello,

 

I'm useing ad9889b as a HDMI transmitter in my project,The video and audio is incoherent,I think there must be two ways to adjust the throughput of audio data to be suited for ad9889b.

 

1:Changing frequency of audio clock (I2S clock,not MCLK) slowly(for example:steped by 7ns and maybe less than it,en...I'm not sure about this parameter,But I think I can do it).

2:Delecting or adding some words of audio data and keeping audio clock at a unchangeable frequency.

 

The first way is easy for me and the other way is a truble thing.

 

My question is:

Is changing frequency of audio clock a possible way?if it dose,what could I do with MCLK?

 

Thanks

 

Tom
