TDA4VM: DCC error

Zhihua Ding

Part Number: TDA4VM

Hi, TI

I meet a issue when testing the DCC feature, but it will report error occasionally, I select external oscillator and internal 32K oscillator as the clock inputs.

I want to know the offset of internal 32K oscillator, I guess it may cause the error.

Thanks！

Hi Brijesh

Sorry, It doesn't help me.

I don't understand below statement, so If I use CLK_32K as input of DCC, can I calculate the seed value base on 32K, or I shall use another value.

Thank you!
