Default Next Step

Hi Ian,

I am very interested in your boards, especially

- IsolatorPi RsapberryPi/ODROID I2S/DSD/DoP isolator and
- I2S to PCM converter board V2.0

My setup:

pi - Allo/Kali Reclocker - DAC 1543 (based on DDDAC)

A Red Baron V5 is on the way.

What would you recommend as next step:
your isolator board or your I2S to PCM board ??

Kind regards

Michael

Gents, can you please help a noob understand how the PCM driver board works with 20-bit DACs, e.g. PCM63, when it receives 16 or 24 bit data. Does it simply pad the words with 0-s or truncates them to 20 bits correspondingly or is there more to it?

It's great we have a I2S to PCM board. Is there a PCM to I2S solution?

Hmm, if this is in response to my question then no, I meant take the "PCM" format such as what you get on the output of a digital filter such as DF1704 and convert it to I2S, basically the PCM to I2S Ian's board in reverse.

Df1704 does output i2s.
What do you think it outputs?

What DAC chip do you want to integrate with DF1704?

For the purposes of this thread DF1704 outputs "PCM", the description of "PCM" is given in the OP, "PCM" most certainly differs from I2S. I want to integrate the DF with Ian's FIFO board.

Ok. Sorry. I personally just think of it as Japanese, or Philips format. Meh!

No worries, too many formats that all seem to do the same thing...
