Ozone,
I'm making a board for 8ch ESS Sabre.
In fact, I already made it and sent the gerbers to the factory. Lead time is 4 weeks now to get the PCB... Will make the first and tell you if it works. I'll have something like 7 spare board so if you like... Form factor is a bit larger than TP's stuff but nothing to worry about.

However, a few points:
- It's not going to be cheap to build (CCHD 950 clock, all C0G/NP0 small caps, all solid polymer (oscons like) big caps, and big Fair Rite ferrites.
- It's all SMD. But I may solder it for you.
-It is routed for the Sabre8, not the Sabre32. If filtering etc.... is done via registers programming, then it will be ok for Sabre 32 too.

There's nothing onboard. Just the chip, decoupling, the clock, and headers.
1 header for inputs, 2 headers for outputs, 1 input for power rails (7... you'll need some regulators. I'll have some to spare too, probably). 1 i2C header and 1 control header (reset, address...).

So you'll have to use regulators (I will probably provide them), I/V (I suggest you use TP's IVY), input stuff (you'll have to go i2s to have 8ch, so you'll probably have to roll your own reveiver board, or check how you could synchronize 8 TP's SPDIF receiver boards?). And for programming etc... You'll have to use your own microcontroller (or computer to upload i2c). I'm going to use Arduino stuff as the simplest way to do it. An Atmega 168 may seem overkill for it but... i2c is so simple on arduino and these boards are so cheap.

Excellent! I'll definitely have a board or two from you. I still have a spare Sabre chip, and I don't mind soldering everything.

I might have to use cheaper alternatives for some of the other components though - especially that Crystek!

Hopefully the Sabre32 is all configured via I2C. I'm guessing it's pin compatible, so might be an easy swap.

The I2C stuff should be easy. I've never used Atmel chips before, but I've got a fair bit of experience with PIC assembly. (picked up a lot of C lately too - not half as difficult as I was dreading.)

My biggest problem has always been getting proper PCB's made - I gave up trying to make DIY PCB's as the copper always falls off after a while.

I've only had two projects sent off to be made in the past - one of them was completely messed up (84 pins swapped!), and the other one worked fine but turned out not to be suitable.

I was also worried about proper routing on the Sabre PCB, so rather you than me!

I suppose that having four IVY modules wouldn't be too bad, as they would stack nicely. I still have seven Sympatico's to build before that anyway (once I get hold of the components).

Please PM me with pricing etc. once the boards arrive.

Many thanks,
OzOnE.

Fine! I'll send you a PM when boards are there. If you just take the board and buy solder everything by yourself you won't be out for much xD. I should calculate it but I think It'll be around 30$ for the board. It may seem a bit steep but it's the price for 4-layers... But considering It'll do 8 channels, it's not that bad.

Yeah the crystek part is expensive. I don't know if it will be pin compatible with less expensive ones. Maybe could you get your hands on some copper strips...?

I'll create my own thread tomorrow and will post "3d views" of these boards. It's rather useless but...

Simple question: I don't have the ESS chips yet, and hadn't the luck to speak to Brian at Shaws. I will try again to call him in the following days, I'd look fairly stupid with my boards but chip to populate...

How did you sourced yours?

I got my chip from Line One Sales, but it doesn't look like they supply to outside the UK unfortunately...

I could post you a chip from here, but no doubt it would cost a lot?

Talking scored!

Sure got tired of "NO Response" with the Sabre
went searching, scored! Just ordered 2 ES9008S from:

http://ecommerce.ismosys.com/orderin...acturers_id=34

Out of China I believe; shipping Fedex, time will soon tell; will let you know.

They even have the eval boards although their too proud of them.

Their eval boards are pretty good looking.
However I first have to spend something like 2300$ for the TC Dice eval board.... sic. Eval boards are a damn thing but always cost an arm...

That's good news these chips start to be more widely available!

[That's good news these chips start to be more widely available!][B]

That means to say the cost of this chip will be more affordable after 6 months, I assume.

Does anybody know why these guys at TP do not reply to emails on their site? I emailed them 3 times in the next 15 days on their website (last time 2 days ago), but with no reply at all. Is this normal, on your experience? Doesn't their email work? Or what else..?
