PCM1808 + DS90UA101(Serializer)

Other Parts Discussed in Thread: PCM1808

Dear....

My board configuration is ===>

PCM1808(ADC)-->DS90UA101(Serializer)-->DS90UA102(Deserializer)-->WM8726(DAC)

256fs and 48Khz Sampling = 12.288Mhz

12.288Mhz is connected to [1]SCKI of PCM1808 and [2]SCK of DS90UA101 simulataneously.

Is this correct?

PCM1808 output looks OK.

However, recovered SCK on De-serilizer is 12.288/2 Mhz (Half Frequency).

It seems that I have a problem in clock scheme.

Best Regards

K.I. Koo
