It's not uncommon for a manufacturer to protect early data sheets like this. Not so much because they are secret, but more because they are not finished. What I found strange was that the data sheet was available on their site for quite a while, then disappeared.

Any spec on performance is already out there anyway, on their own website, downloadable in excel It probably sais more than the datasheet...

They also provide a free schematic of the ESS website. You could even copy that and have a DAC without the need of a datasheet if you wanted.

A few days ago, this link somewhere on this thread did actually still work, so I'm guessing it still does. If ESS does not want it public I suggest that the link is removed. I'd sign an NDA if I need to.. no problem.

Imho the datasheet does not contain any shocking information that should be hidden from the public, so I guess that Russ is right in saying that it's not public because it's preliminary..

Hi Dustin,

Where can I find some info on the ESS Sabre Ultra 48pin chip?.
From what I have seen of limited info it appears to be nearly indentical to the ESS Sabre Reference 64pin chip,
but with lower channel count?

Raymond

there are several errors on the datasheet. particulary where it lists what the register defaults should be. register 14 and 15 tell the wrong defaults.

To people waiting for my board: it will take a bit more time to complete it.

Why?

Just because I have to fix my *&#$ computer.
The new hard drive was in my mailbox this morning, I'm trying to rescue all my data :'(

I'll now stop polluting this thread - but be sure that I'm working on it.
When the projet will be ready - just to check again everything, I'll post a new thread.

Thanks,
Nicolas

Default Denon DVD-1920 DSD MOD

OK for those of you who don't mind risking a Denon DVD-1920 and want to get DSD out of it...

Here is how I am doing it:

There are three vias at DBK,DSD1,DSD2. Solder a tiny wire into each via.

I am not sure how I will run these to the panel, but for now just to test the DAC I just used allegator clip jumpers to wires which are installed in the DAC.

It actually sounds very good despite the makeshift wiring! It is definitely much better than the stock DAC, but that would not actually take much.

The DVD-1920 is much easier to modify than the DVD2910, so I would go that route personally.

Cheers!
Russ

Here is a picture of the wires soldered into the whiskers.

Here is the rig in use. Keep in mind this is not by any means a finished project. I just wanted to show that it works.

Interesting side note...

If you take out the useless little analog section at back left corner of the player there is more than enough room for a Buffalo/IVY stack and two power supplies and a couple toroidal trafos. Sweeeet.

Great posts Russ, just what I was looking for I think i remember reading somehwre in the thread that you tried DVD-Audio out as well. Where did you tap that?

Edit:
Would pin 46,47 and 50 get me PCM output and could I run that to TP SPDIF module?
