Hi,

 

Do you have any idea on the value of internal impedance for ADAU1761 and ADAU1401A BCLK?

According the MEMs Mic application note that we received, we need to match the impedance between BCLK and the MIC clock to prevent causing degradation of Mic performance and probable EMI issue.

 

Thanks.
