Hi there
May I kindly ask for your opinion on what the ADC (maybe also: pre-amp) of your choice would be to provide an FPGA with a (relatively) noise-free input from a Knowles SiSonic SPU0410LR5H-QB
output signal range: 20-85kHz
ADC sampling rate: >=256kSPS -1MSPS
ADC Output: PCM and or I2S
I would like to acquire, buffer, modify and output digitalised sound (as a stream or on SD-card) with an intel FPGA.
the bus between the FPGA and the ADC may have up to 16 signal paths.
I am also interested in an ADC I can easily use with my (amd64, Linux) workstation or even raspberry pi (clone) to ensure I get that part of the project right.
I will share all documents on Github and I will also share the source code for the FPGA (license tbd, probably MIT).
Currently I‘m considering the AD7768 but I‘m not quite sure.
It isn’t my first FPGA rodeo, I am a retired automation engineer who has always had time for tinkering.
It isn’t my first dabbling in analog circuits either, but this time I‘m having a harder time.
Thank you for taking notice!
