Re: Re: Deriving I2S from Sony CDP
I have a player that has CX23034 in front of the DAC and with bypassed CX23034 it still works.
Now I want to use the DAC of that player with CS8412 receiver with or without the CX23034 . Is it possible ?
The DAC uses bitclock, wordclock, data and L/R clock.
Or would it be easier with Yamahe receiver YM3623B ?
Why does the Yamaha use a crystal ? Better ?

Not really a name, it is inside a Teac ZD3000 and uses CX23035 -> CX23034 -> Teac chip which has inputs L/R clock, L/R clock inverted, data, serial clock, word clock -> 2x PCM53.
I post schematic.

You need to reformat the output of the receiver to match the input or the output of the CX23034.That means going from a 64Fs clock domain to a 48Fs one.
Send 32 bit per frame data to a shift register, copy into another register and read out with new clock and 24 bit per frame ?
Isn't that recklocking as side effect ?
Also CS8412 provides only LRCLK or WCLK, not both at the same time.

1. Use a Sony SPDIF receiver that outputs the necessary format.
2. Use a generic SPDIF receiver and some logic.
3. Design your own SPDIF receiver.

Is this the chip ill need for this Sony CDP620 to make is2 ? Excuse my lack of knowlege on this matter im new to this part of the audio field.

I'm Sorry.
Can you help me with a schematic and some parts to get the is2 and my dac working with that sony. ? Is it realy worth it ?
Is there other things i can do for mods instead ?

Ok im not going to take the external dac rout on this cd-player. I like this cd-player a-lot. Can any one suggest some mods i can do to it.. ie replace caps etc etc change op-amp's things that can life'n it up if possible. ? Id really appreciate it.
Modifying a circuit is not an easy task, it requires experience and is usually done by trial and error where parts are substituted in a circuit and listened to. In that way it's really hard to provide any specific recommendation for a given unit, uness one already performed proven mods.
Here's the link the mods I did on my LM37 transport: http://www.diyaudio.com/forums/showthread.php?postid=896134#post896134 , they worked out well and I can surely reccomend those ones. Regarding the Sony transport I would be clueless what to do.
This is mostly a reply to an e-mail enqiery you sent me a while back. I also like that particular Sony transport, but didn't do anything about it yet.

Applies only if it's a normal Sony (In fact, every Sony CDPs I opened) :
CM made a circuit to convert 3 different EIAJ formats to I2S.

As for SPDIF, in a Sony CDP, it's not on the digital filter, but on the drive controller that you're going to find it. Try to find a DOUT pin on the transport PCB or the chip between the transport and D/F if there's one.
You have a lot of chances to find a DOUT pin on the DAC PCB and transport PCB. There's going to be an MD2 pin also, and you need to pull it high, make sure it's not presently grounded.
