ADC

I have not been paying much attention to digital for a bit now, but I have a need to put together a ADC, FPGA and DAC on a board for an idea (its to provide a delay element for Marks speaker experiments). What is the current flavour of the month with ADC and DAC chips. A quick google, makes the PCM4202 look a candidate.

Any view?

Sorry Nick, I can't help with chip recommendations. But the board sounds very interesting. Could you use it for RIAA phono equalisation with zero phase shifts?

Like the way the Mytek sounds Nick, chip is the Sabre 9018 K2M, not sure if it's available for diy though.

Though I guess the package is not DIY friendly, but TBH, the moment you enter modern FPGA land, you leave the possibility of soldering by hand. The FPGA I was looking at a 238 pins in a BGA.

Its the ADC that is the key though, there are loads of DAC options.

Mytek also sell ADC's. I believe the 192 uses AKM 5394A. Lots of love for this ADC from what I've read.

I dont see why not. The next step is to wrap the ADC and DAC around a dev board like this.

Though at the moment I am fighting with USB drivers and not got much further than creating a micro blaze processor on it and sending Hello World out the USB port.
