ADAU7002 PCLK is not generating

Hi All,

 

 

I am using ADAU7002 chip for PDM to I2S conversion. I am using PDM digital mic (MP34DB02) for input.

 

I checked BCLK and LRCLK. BCLK(Bit clock) and LRCLK(SYNC) frequency are proper and their values are 1024MHz and 16KHz respectively. But ADAU7002 is not generating PCLK on output pin. 

 

I also checked IOVDD voltage which is 3.15V. 

 

Any hint on this issue?

 

Thanks,

Vivek
