Hi all, one of my customer is using the TLV320AIC33 to generat an audio signal at 48KHz from a 10MHz (using a PLL inside the Encoder).
at the HPROUT the signal is updated at 66KHz (it is possible to see the output of the DAC with signal steps at 66KHz).
The HPROUT is decoupled and then feeded in to amplifier.
Below the registers configuration.
Can you please help to understand the root source of the 66KHz ?
thanks,
Domenico
