Cheers for making a attempt directly. Hopefully the threaded versions start populating on some distribution channels (primarily Mouser). But since they have demanding corporations and governments, the chances may be quite low.
I just meant the latest and greatest of their model, the 3400. The 3000 may have been out on the market longer. The 3400 may not even be released yet.
It's too bad, it would be my #1 choice too as German and European engineering is really appealing. I can't imagine how fast the Graphene will charge with the UcPure. If it takes an hour to fully charge a non-Graphene Ultra Capacitor, maybe a few minutes charge with Graphene? That would make a pretty robust solution.
I'm a good year behind in these Ian projects, so I may skip out on the UcPure as I just realised you need a third-party balancing board after skimming the manual. I just want to keep things simple for now and slowly learn. So I will try to hold out for Skeleton Technologies in late 2022. I have enough on my plate ATM to keep me occupied.

Thanks. Since I run exclusively Redbook on the RPi, the 5 MHz is all I will ever need along with the SinePi.
It's possible afaik. But i also wanted to know if the 3.3v regulators to the clocks can get bypased so only the clocks get 5v. Tentlabs seems to preform better on 5v. But maybe there are other sugestions. But not a lot people on this topic seems te be interested in this option.
You can feed 5V to FifoPi clean side if your clocks work at 5V, the rest of components are 5V tolerant.

To do so, you will need to bypass the LT3042 LDO on the Q2.
Please see the user's manual of Q2 for details.

Already have seen that manual. Thought it was fot Q1 alone.
R58 and R59 needs to be bypased. But there is a max. voltage warning for 3.3 volt. I can ignore that for Q2?

Hi Ian,
I noticed LapTech has an OCXO section. Because I moved on from MagicXtal, looking for alternatives for future use.
The OXO214 - 1000 may have worked out, but unfortunately they only have one freq and is 12V. They have under-performing 3.3V or 5V DIL, so will have to pass until they release an "optimised" version.

Anyways, I stumbled upon another product that may look interesting for SinePi pairing:

Hi A123, I looked at this as well. Point is that the phasenoise round 10Hz is significantly worse than the Andrea clocks. 115 vs 150.
"You can solder a 0R 0805 jumper resistor or just a short piece of wire at positions R58, R59 which are located at bottom side of the FiFoPi. CRITICALLY IMPORTANT NOTE: After you short R58 and R59, the ABSOLUTE MAXIMUM VOLTAGE you can connect to J5 is 3.6V!!!! Any higher voltage means you will likely damage your FifoPi and clocks."
Ian, when you are back, can you for sure confirm that i can connect 5v after bypassing R58 and R59 with the Q2 J5 (assiming the clocks can handle 5v)?
Ouch. Okay I'll keep that in mind when checking the clock specs. I was just focused on the SMA connection now that the SinePi is soon to be released, but for that the Neutron Star or Andrea's is clearly the better way to go.
I'll stop getting sidetracked with clocks and just be happy with Andrea's clock.
Thanks for this data and I now have some of these. All I need now is the group buy to start to get the UcPure 😉
