ADAU1701 IIS input 192Khz signal to enable filter, DAC playback has noise
Specific operation description: As shown in the schematic diagram above, currently only one General 2nd filter is added, set to hpf and 60Hz corner frequency. Set the sample rate to 192K and the DSP c

ADAU1701 and multible i2S inputs
Hello again, I mangaed to get a APM2 from wondom (ADAU1701) up and running with a PCM5102 DAC from aliexpress and a WM8782 ADC from Audiophonics. This is all described in detail here: ADAU1701 as mast

active two-way speaker with 1701: help for loudspeaker management and protection
Hi all, I built an amplifier module for an active two-way speaker with powersoft digimod 1500. I would like to create the firmware to better manage the speaker by protecting the speakers so that they

Phase modulation with ADAU1701
I need to design a sinusoidal VCO with very deep phase modulation (multiples of 2*PI range). The VCO block under Sources/Voltage Controlled doesn't have phase input, hence I hoped to use trigonometric

Generating overtones with fixed phases in SigmaDSP processors
Dear colleagues! I would like to share my experience in generating overtones (harmonics) of the sine tone with fixed phase relationships in SigmaDSP processors. For example if we need to generate sine

How to introduce phase delay to a tone generator
Application: Generation of an error signal. Problem: I want to introduce a fixed phase shift between 0 and 2*pi in the sine waves of two sine tones with same frequency (10kHz..20kHz). The sine tone ge

MultiPurpose pin jitter on ADAU144x
I'm finding that I can't get a stable fast (10kHz) square wave out of the MultPurpose pins on my ADAU1445. My scope is telling me it's rock solid 10kHz but I see it scooting around. When I use the pin

Frequency Divider
Is there a module, or combination of modules, which can divide a signal from the frequency generator? My application includes mixing some signals from a sine gen source (or external source) but some o
