well , i rephrased Gordon's msg (without his approval) , i definately think he is talkin bout an ADC:

- ESS released yesterday the 32 bit version of the Sabre, AND, you heard it here first: THE first ever 32bit ADC...



32 bit wordlength is more common than the 6bit 5mhz comnig from a PCM4222 so it makes enough sense to me... I also remember Dustin said it'd be fun to start out with an ADC project, esp since even audio precision 2 uses bog standard cirrus converters.

/Me would like a 32 bit DAc version of the Sabre, it would allow for digital volume control.

The Sabre8 also has digital volume control. It does it at a higher bit rate than the 24-bit output (IIRC, it's done at 44-bit resolution). I am not sure the Sabre32's volume will be any different, but it's possible.

This is very interesting, i must have missed something then
So it coudl be done in hardware in the dac without loss.

But how could it be implemented in software without the obvious resolution problems? Would that be possible?
AFAIK connected to a computer, the Sabre is seen as a 24 bit sound device.

About ES9008S in hardware mode.

It is stated in the datasheet that in this mode, the chip would only accept I2S data. And the default register for bit width is 24bit. Does this mean that hooking it up with USB receivers like PCM2706 is not possible? PCM2706 has 16bit I2S output.

Also for applications using USB receiver and PC as a digital source, I do not know if the output would be 44.1kHz or 48kHz, the choice of system clock seems difficult to decide. Some previous posts suggested the system clock needs not to be a multiple of the digital source, but the clock should be as fast as possible.

I would not advise using the chip in hardware mode at all.

Its automuting will drive you nuts.

The Sabre32 resolves all the issues that made hardware mode difficult with the Sabre8.

If you must go hardware mode then I would use the Sabre32.

Cheers!
Russ

Oh man. I'm so tempted to start a project using this chip. But the microcontroller part is a real downside for me.

Any idea of the ETA of the new chip?

Can you get the old chip without jumping through hoops ?

Yes, there's a group buy thread that's a few weeks (months?) old. MOQ is 5, and the chips cost around $50 each.

There are two suppliers for UK and Ireland, if you meant if I can get ES9008S or not.
