Will there be soldered versions?

//

Since my free time is almost zero, I would avoid to provide a soldered version.
Furthermore I would spend this little free time for other projects to share with the community (power supply, ultra low input impedance IV tube dac output stage, maybe a player system SD card based with discrete R2R dac, and more).

There are 10 members asked for soldered version, so I ask all other members:
is there anyone available to solder for other members?

If yes, please let me know, so I could ship all the relative PCBs and crystals to someone that will collect them, and finally he could ship to each member the finished boards.

Just to understand - this will be; boards, crystals and BOM - nothing more?

Nice thread, folks! My $0.02:

I agree with 1audio about adding a trap to keep the oscillator from starting up in the wrong mode (on the wrong harmonic). This is rarely a problem if you are building just a few units, but if you go to mass production, you may encounter crystal batches that just want to start in the wrong mode. Ask me how I know 😉

The dielectric of the tank caps matters vis-a-vis microphonics. I've had good luck with mica, but they are somewhat hard to source. If you can devise a rig to actually demodulate the jitter and listen to it in real time, scratch the top of each cap with a dental tool to see which is most microphonic, then swap to mica and compare. As for listening to jitter, I use a Meitner LIM detector, but in some cases you can just drive the clock into a pair of passive headphones that will do the demodulation. You can optimize PSRR this way after injecting the PSU rail with an AC probe tone.

I didn't see any mention of duty cycle, but some converters are very sensitive to it and need 50/50. This is a good reason to do a double-speed clock and divide it by two. It is particularly important if you clock distribution scheme has any asymmetry in rising vs. falling edge speeds, which will degrade the duty cycle.

Also, I see the design uses a resistor divider to generate the DC slicing threshold voltage that is coupled to the first inverter. A neat trick is to instead use a spare inverter and short its input directly to its output. It will then "find" its own ideal slicing threshold, which you can then couple to the front end inverter. For this trick, it is usually good to use a xxU04 and use an inverter in the same package as the slicer to get good matching. If you couple this threshold voltage to the input inverter using a pulse transformer, you have a very nice bulletproof S/PDIF receiver.

Just to understand - this will be; boards, crystals and BOM - nothing more?

Exciting... Korben, we have faith in you!

Hi TNT 🙂

I'm collecting informations about tasks to perform.
Does Post#106 contains final BOM & PCB ?
Is Post#172 the final daughter board ?
Seems doable to me, let's have some talk with Andrea.
More to come soon.

Regards

Phil

I can testify that korben did an excellent assembly job on ES9023 Subbu DACs 😀
