I am near completing my board using WM8805 (in HW mode) and AD1895 interfaced to BCLK1, LRCCLK1, SDO0 and SDI0 of the ADAV4601.
The system documents mentions the following:
1. The ADAV4601 internally operates at multiples of a sampling frequency (Fs) of 48kHz. When creating audio flows in
SigmaStudio it is important to set the sampling frequency of the audio flow to 48kHz.
Is it mandatory to use 48KHz? Can I still use other sampling frequencies like 192KHz using SigmaStudio for a custom design flow?
2. USING A CUSTOM FLOW WITH THE APPLICATION LAYER
We strongly recommend this approach. The advantage of using the Application Layer is that it automatically takes
care of safeloading. It dramatically reduces the amount of I2C writes to the part freeing up the I2C bus in your system
and simplifying microcontroller code.
Can I have a link to download the Application software? I would like to get familiar with the interface and its capabilities before my fabs arrive.
