FDSP samplerate and SigmaStudio Fs setting

Category: Software
Product Number: ADAU1787
Software Version: 4.7

Hi

My project is running 192kHz on ADC01 used for FDSP and 48kHz on ADC23 used for SDSP. In the schematic editor I'm having 48kHz (default) as the sample rate.
When setting the filters transfer function in the FDSP I experience the frequencies is shifted a factor 4 (192/48) e.g. a dip at 100Hz using the parametric EQ function is dipping at 400Hz.
Are there a setting that can tell the editor that the Fs of the FDSP is 192kHz without changing the SDSP which is correctly using the 48kHz as Fs? 

All the best

  • Hello John,

    This part has been released for a while and this is rather basic and I am guessing someone would have noticed this by now. There may be a register setting for clocking or something like that which is in error. It is very easy to do! Could you provide your project for us to look at? If it is confidential then send it via a PM. 

    Thanks,
