Hi Russ and Brian,
I have read this in the Retro thread:
It didn't seem appropriate to ask there for the progress, so I thought I opened another thread for this module.
Are those ICs already available?
Did you guys make any progress on the modules itself?
Thanks and looking forward to it!

Neither the datasheet nor the chips are available yet, but we are checking with ESS on a regular basis
A little bit old, but this is news to me:
ESS Technology Introduces Flagship SABRE32 Reference ADC!
It's also listed at ismosys, although I do not know if this means that it is already available.

Russ,
there are a lot of settings one can change in the ADC. Will you provide some jumpers for these? If so, which settings?
Would be cool to have the RIAA option available. Then one could connect a phono cartridge, have a balanced 32bit/384kHz ADC with built-in RIAA decoding network, and get I2S out which is then fed to the Buffalo2,3

It will use a little controller like the B3. And one could use AC2 with it. The RIAA option will definitely be available.
Russ, I was wondering, will you be using the same developing process as for your
USB-module, i.e. you'll show it when it's ready, or are you willing to involve the diyAudio
community in the development?

I never refuse input. I have a couple of higher priorities at the moment in any case. 🙂
Here are some things that would be nice to see implemented:
* the possibility to set the sampling freq to 44k1, 48k, 88k2,96k,176k,352k and 384k via DIP switches or by SW
* sepate digital and analog power supplies (maybe use the AVCC module)
* Both I2S and SPDIF outputs
* Two LEDs that show if clipping occurs for LE adn R channels respectively
* A very good clock
* have the possibility to disable the right or left ch datapaths and ADC
* set the clip detector level threshold
* use mono or stereo mode
* not to use the DC blocking filter as that can be done in the music software one uses
* set the IIR BW
* have some form of hardware protection at the four inputs (diodes+resistors for ex)
* no dithering
* RIAA usage possible
* have some LEDs that show the sampling freq used
* have a simple OPamp-based input sectio for all 4 inputs but it should be possible to skip this section and go directly to the hardware protection circuitry bypassing this analog section
That is about it, but there are a few interesting functionalities that I not really understand:
* it is possible to get the digital signal directly from the ADC overriding all other output settings
* set the DPLL multiplier
* select the 2nd stage ASRC IIR filter BW
/IR

Nice list. I think you will be happy that most of it will be hit. I will have to do some checking on the rest.
Cheers!

I'm sure there will be a LOT of interest. If you guys are able to make an ADC to go along with the Buffalo III, you would be the only 32-bit game in town! Except for MSBTech, but who can afford their stuff?????
Just bumping to also express interest.
I don't need much of a feature set, just a well implemented ADC system with SPDIF/AES out and the ability to set it to 96kHz.

ESS contacted us and let us know that there is a hardware revision to the chip coming (including a change to the pin-out) so we will be delaying this module slightly.
That's no problem for me, but a 2012 release would be nice, so I can use it for a while before 21 Dec.
