Query about PLL Lock in ADAU1761
Hello, we do use ADAU1761 in our module. The masterclock ADAU1761 MCLK is provided by a MPU , MCLK frequency is 26MHz. There are 2 power modes of the MPU (RUN and Low Power). The MCLK signal from MPU

Shift incoming I2S data left 7 bits
For reasons that are too long to explain here, the I2S data is arriving (logically) shifted right 7 bits. This is fine because it's really just 16 bits of valid data. Before I can use the data I need

Inquiry on ADAU1761 extern MCLK Clock Synchronization and CRC Verification Method
Hello Teams, In a custom project, the MCLK for the ADAU1761 is sourced from an external chip (referred to as Chip B). Since the main control chip (MCU) cannot determine the exact time when Chip B outp

Trying to output sound on headphones from I2S signal
Hello, I send an I2S signal to the DAC input of the ADAU1761 (through J6 connector on the ADAUX61EBZ board). I checked it with a logic analyzer and I can see it correctly. I'm using the onboard oscill
