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

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!
Russ

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.

A built in USB output would be great.
