Help needed with the PCM63.

[miklos]

Hi,
Looking for help with a DAC board which came out of a Sony DAT and have two PCM63 DAC-s on it.
I would like to make a stand alone DAC of it with SPIDIF input. I don't know digital at all, so I'm looking for a simple solution, a not to complicated circuit or a readily available (maybe ebay) converter board. Any help would be greatly appreciated.

You need a DIR board which can output 16bit Right-Justified data stream. Look for WM8805 or AK4113 digital receiver board. With proper setting, they will work for you.

Which Sony dat model had PCM63? Thought I knew all of their models.

I would say that the DIR9001 is the simplest DIR to implement for this sort of project. Kit boards are available on ebay that are easy to assemble & work well.

Thanks both of you, I will look into this.
The PCM-7010 has the PCM63 and the PCM-2500 has the TDA1541, also the DTC1000.
All early models from the 80's.

Hi again,

I looked the AK4113 on ebay and the description says: AK4113-Digital-Receiver-Board output Right-justified, Left-justified and I2S.
Some years ago Elso Kwak writes:
"The BB chips expects data in the binary two's complement (BTC)
format with the most significant bit (MSB) being first in the
serial input bitstream."
Also the SM5803 digital filter on my board accepts 2's complement or COB, MSB first signal.
Will this ebay board work on mine, or I have to go for one of the other receiver ones mentioned above.

Thanks.

You don't need to care about BB PCM63PK. Bridging between DIR and SM5803 is what we need to do. Here is the input timing chart from SM5803. It's right-justified MSB first (SONY format?).

Thank you Canvas.
As I mentioned in the my first letter, I don't know anything about digital logic. The timing chart you sent, doesn't say much to me. On the top of it I also have problem with the digital jargon, and short forms.
On this thread cm has a circuit for an I2S to EIAJ conversion, I could build that and feed it from one of the DIR chips mentioned.
Would this work?:
I2SoverUSB - I2S over USB Audio

Yes, this I2SoverUSB is even better. If you have this board, you don't need SM5803 anymore. Just connect the wires directly to your PCM63PK, and it will work.

The only problem remains the spidif, with this board USB playback from a computer is solved. Thanks.
