ADAU1966A Register Programming Sequence

Question asked by vignesh.sridharan on May 31, 2018

We are using  ADAU1966A  in system design with direct master clock mode by following clock sequences. 

   MCLK : 16 MHz

   DBCLK: 1 MHz

   DLRCLK: 31.25KHz 

   sampling rate FS : 31.25 KHz

   I2S Left Right justified

We need help with programming the registers, for the above mentioned configuration. 


What we have currently tried, 

PLL_CLK_CTRL1 reg 0 (0x00)       - 0x01

PLL_CLK_CTRL1 reg 1 (0x01)       - 0x2B

PDN_THRMSENS_CTRL_1 (0x02) - 0x82

PDN_CTRL2  (0x03)                        - 0x00

PDN_CTRL3  (0x04)                        - 0x00

DAC_CTRL0 (0x06)                         - 0x00

DAC_CTRL1 (0x07)                         - 0x00

DAC_CTRL2 (0x08)                         - 0x06


With the above register sequence, we can read the temperature from 0x05 register correctly, but we not getting any audio output at the DAC.



1) Is the above register values are correct ?

2) Is there any sequence to be followed to be followed while programming the registers


Thanks in advance
