Hello, I'm working with the ADAU1442 and the eval board from Analog Devices.
I have made my aplication and run very well if my fs=48KHz.
I need to work at fs=96KHz for that I have modified and have propagated the fs on the SigmaStudio Schematics sofware and also I have modified the register "Star Pulse select" going to fs dual mode ("internally generated 96KHz").
My questions are:
1.- Am I working at 96KHz?
2.- What happen with the DAC's, what are they fs?
3.- Why my aplication only works if the serial input and output ports are configured as Master, 48KHz clock?
4.- When I messure my frecuency response I can find a little differences bettwen the f. response at 48KHz that the f.reponse at 96KHz, that differences are bigger at high frecuencies, this can be because I'm not working at 96KHz as I supposse or because my DSP is working at 96KHz but not my DAC's?
Thank you for your answer.
