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?
