Has anyone tried this ?

ES9018 32bit Audio DAC PCB Kit | eBay

I'd like to build an ES9018 with a 22.5792Mhz clock (CCHD-957) to play cd and sacd (44.1 and 88.2 Khz sources) and it looks suitable - it says it can select synch/asynch with a jumper. What do you guys think ?

Thanks,

Tom

Default DAC Kit

There is a vendor forum for this:

ES9018 32bit Audio DAC kit USD89.95

(A little) more info.

Thank you Ian. Unfortunately there's not much more info there though and no-one has posted anything about actually building/using it either. However, it seems it is a new design so i guess i shouldn't be surprised.

I read on this thread that Bunpei and others have used ES9018 synchronously with 11.2896 and 22.5792 clocks. Should I get the vendor to set anything else in the register so synch mode works as well as possible, and if so, what other settings work best for a 22.5792 clock ?

Sorry if this is detailed in the datasheet but I haven't been able to get a copy yet - kind of crazy that a four year old part still has no datasheet for download.

Thanks for any help !

Tom

I wouldnt use such slow clocks with ES9018, even if only for 44.1 and honestly I think the layout for the PCB is pretty ordinary

I also wouldnt use ESS without access to some of the settings, without that there would be no way to swap between PCM and DSD, they will both work with the right connections, but the digital filter will not be right. the DPLL will be default and how do you plan on running sync mode with DSD? where are you pulling the clock from? its not synchronous simply because the clock speed is an audio multiple

thinking of installing it in a DVD player and using its clock?

Hi,

I plan to use it for a QA550 sd player that has a Vanguard 11.2896 clock, but the Crystek is better, so...

I would also like to use it with a WM8805.

I guess the best way is to try and see ?

I've already purchased one along with a fast USB to I2S board for this DAC from the same vendor, and received both of them today.

DAC board looks neat! The hybrid components are fairly apart from each other, I don't see a big challenge in putting them on, even few mandatory SMD parts. There are few ambiguous spots that I couldn't figure totally yet, though! Few components need to be identifed or clarified, but I think they don't pose a problem either.

I believe this board have already attracted some DIYer's attention, there will be more to respond here soon!

In any case I'm not very experienced with DAC boards, and have limited experince with SMD stuff,but I think it would be much appreciated if someone who is more apt and experienced can share the experience with this board.

Hi, Tom,

As for a synchronous MCLK frequency, I think 22.5792 MHz is enough for fs <= 88.2 kHz or DSD64 even if you want an OSF=On.
However, for an asynchronous MCLK, I'm afraid 22.5792 MHz is too low.

In my case, I usually use MCLKs of 90s MHz for playing DXD and DSD256/DSD512.

Thanks Bunpei ! The DAC has a jumper for synch/asynch so I can hopefully fit an xo socket and manually change xo and jumper when/if I need higher bit rates.

I saw on another thread that Joe R is using a 125Mhz saw xo for asynch, so I think I'll try that too.

I remain unconvinced about the 125MHz SAW, running the dac chip 25% over max speed spec for.....? its still async

I am observing values of 8 and 9 on register 27 (ES9018 Status (Read-only)) on my EV board. In the Help of the Sabre GUI I can only find that values 0-3 are described and 4-7 are reserved. Where can I find more detailed information on the meaning of the ES9018 registers and register 27 in particular?
