Sinus generator
Hi! I have a question concerning an ancient consult: using an ADAU1701, I want to design a sinus generator to generate an sinus of 40KHz, having a sample frequency of 192 KHz. I can't use the block "Sine tone" because it divides in four the frequency and this one it's not enough for my projet. In the ancient consult, the answer was a circuit (http://www.earlevel.com/main/2003/03/02/the-digital-state-variable-filter/) but i reach to have 24KHz only with it. Are there others options?
Thank you.

The restriction on Sine generator frequency was removed in recent versions. You can easily implement a 40 kHz tone now if your system sample rate is set at 192 kHz.
Make sure to follow the instructions carefully to set your system sample rate:

The division by 4 probably occured because your DSP core rate was not properly set to Quad Mode.
