Honestly I am not sure why I am even concerning myself with DSD...

Is this a stab directed to me? If so, I can answer how to use the DSD input.

Not particularly Just noone seems to know how to make a module that would take DSD from say a DVD player that supports it and feed it into the DAC. Was thinking of a module to use that would accept firewire or HDMI as I believe thats the only way to use DSD with SACD and what not.

Russ,

I will put together a sorta mini app note on how to wire the chip up such that you only need 3 pins connect and you can get all channel to parallel together in all 3 modes. I know I should have just made it easy programming but that would be no fun right? No just kidding, I really overlooked that and its my mistake. But for now, you can short

DSD5 to DSD1
DSD6 to DSD4 to DSD2.

With these pins connected like so, there is 2 register setting you can make to get stereo mode for SPDIF/SERIAL/DSD input.

Also, pin25 on your schematic should be connected to 3.3V

I will get you the register settings soon.


Thanks

Dustin

Thanks Dustin,

That will be great, but I was also hoping to support use of the PCB without a microntroller (at least for I2S mode). Would this still work?

Thanks again!
Russ

If you just want I2S and nothing else, then just simply wire the RSD0/RSD1/RSD2/RSD3 all toggether and powerup.

Thanks

Right, I understood that, but what I meant was I want to be able to support both operation with a uC and without.

What I am thinking now is that I will likely just go ahead and add a uC to the board.

Cheers!
Russ

Ah thanks for that tip, somehow I missed it!

The more obvious name would have been "Project Light".
