The Schematic of CS8414 --> DF1706/1704 -->PCM1704

Dear all,
Where can I find the circuit of above combination?

Thanks

Hi XTAL,
You can find o interesting report in the
ELEKTOR review, Spanish versión are the
numbers Nº:235, 236,237 but I think that you can to intoduce in the official web of elektor but I don´t sure if the elektor have a www page.
If you have any problems about it, I can sending to you the Schematics, but the article are in spanish.

Please email to me for reference.
Thankyou very much.

Hi Jesus,

sorry to disturb you one more time, but this article seems very interesting to me. I am right now stating to develop a DAC with CS8420+DF1704+PCM1704 and it can help me. I have no problem in reading spanish.

My e-mail is: joao.yazbek@uol.com.br

Thanks in advance...

check the application notes for the DF and PCM parts - There is a demo board available for $399 US that will allow you to experiment with various modes. The app note for the board includes a schematic and board layout should you decide to DIY it.

Link to app note: http://focus.ti.com/lit/ug/sbau013/sbau013.pdf

several language options are available if you go to ti's main site - search for DEM-DAI1704 for the board info.

It's funny how so many circuits you find on the web are just minor (if that much) variatons on application note designs. I never saw teh Elektor design so I am not commenting on that.

 

[jyazbek]

I will take a look at this doc.

Thanks Bob

CS8414-DF1704 and PCM1704

Hi Joao and Xtal,

I were Sacaning the inform of the elecktor
report spanish version but it is 10 pages
in PDF format and the total is 7.5Mb it is too munch and Joao your email refuse its.
Xtal and Joao it is aprox, 750Kb for page if your prefer that I ´ll sending page to page it is ok.

Or if your known onother compres form
tell me, not with winzip.

Hi Jesus,

My mail box has 20 Mbytes, I could not understand why it refused your e-mail. If you can try it again, send me in two or three separate files, I think that it will work fine.


Again, thanks for the attention.

The Schematic of CS8414 --> DF1706/1704 -->PCM1704

Dear jyazbek,


I had one question & hope U can give me some advise.

1. CS8414 + 8420 + DF1704 ( 24.5760M Oscillator ) + 2X PCM1704.

2. CS8414 + DF1704( 24.5760M Oscillator ) + 2X PCM1704.

3.CS8420 + DF1704 + 2X PCM1704.

Which one U prefer!!

pls give me some advise!

thx

Don't use CS8420

CS8420 and nearly all ASRC is rubbish, sounds bad.
Use AD826 and LT1027 as the power supply of PCM1704, which really sounds good.

Do you have any schematics of those available? I'm working at the moment on PCm1704 DAC and better PS would be interesting to try.

Dear AD1865,

How to do it,

pls advise.

But...... AD826 & 1027 is Op-amp. 8420 is digital receiver!! Looks Was different. How to do???????


sorry for my bad knowledge. I don't understand how to do it!


thx

the ML 30.6 DAC has this type PS.Maybe you can re-draw its schematic😉 😀

An externally hosted image should be here but it was not working when we last tested it.

 

[AD1865]

I guess the schematic like this

But without R1.

Re: I guess the schematic like this

Hi , AD1865 ,
You try the schematic ? How about ?
Thanks!😀

 

[Peter Daniel]

From LT1027 datasheet. Looking at ML picture, it seems like they used indeed same approach (but without trimmer). The resistors are 2k.

 

[AD1865]

The PCM1704 PCB has complete

DIR1703+DF1706+PCM1704.
Power supply and bjt I/V are on another board. May be next week i can complete all of the work and give you evaluation.
To Peter, the resistors are 2k or 10k? I can't distinguish them.

 

[Peter Daniel]

You can get hi res pics from ML site. You can see the even small sratches on those parts.😉

It is 2K
