I use ad8989b to transmit video and audio signals.

The audio format is I2S.

The I2S audio sample frequency is 48KHz

MCLK is 12.288MHz

SCLK is 3.072MHz

The video clock is 74.25MHz

The audio clock and video clock are truly asynchronous.

When I transmit high frequency audio signals,I can hear much noise from TV.

I don't know my configuration is right or not.please help me,thanks.

Enclosure is configuration list.
