The Well Tempered Master Clock - Group buy

[gabor80]

Andrea!
In the BOM xls, do I have to order the second sheet (XMFR) parts (mini circuits) too?
Mouser cant find that part: ASK-1-KK81+
Thanks

 

[andrea_mori]

Mouser does not sell Mini-Circuits parts in all countries therefore you have 2 options:

- you get from Mouser the parts you can find and then you get the missing parts directly from the manufacturer (pay attention to the MOQ)
- you get the Transformers kit available in the order form for all oscillators and frequency doublers (it includes all the requested transformers for each semi-finished board)

Sorry, but I cannot manage partial order for RF transformers (all or nothing).

 

[gabor80]

So are these Mini-circuits parts in the transformator kits too?
I believed just the epcos coil, what I saw on the pictures.
So if I understand well, I need to order just the BOM sheet parts in the xls (from mouser) and the suitable transformer kit from you, no other mini-circuit parts to order yet? (and naturally the semi-finished boards).

 

[andrea_mori]

Yes, you have to order:
- BOM parts from Mouser
- Semi-finished board from the GB Order form
- Mini-Circuits RF transformers (second sheet of the BOM) from the GB Order form (or by yourself from Mouser/Manufacturer)

 

[gabor80]

Its clear now, thanks!

Almost two years ago I started a thread to investigate the opportunity for a diyer to build a real low jitter oscillator.

Nowadays a couple of GB have already gone, but since it seems there is still enough interest, to keep the discussion tecnical only on the main thread, I decided to start a separate thread for the group buy.

You can find every technical detail and related discussion on the master thread at The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator - diyAudio

Hi Andrea

Thanks for providing the overview documents, they really help a lot!

Do you have the boards in stock? How many boards do you have? What is the delivery time? Is there an ordering deadline? I am just trying to figure out if I have to be quick with placing my order or if I have more time to think about the best option for my DAC.

 

[andrea_mori]

I have no boards in stock, I will start the production at the end of the GB.

The delivery time depends on the crystals manufacturer lead time, at least 6-8 weeks.

I believe the GB will remain open until the end of this month, then I will place the order to the crystals manufacturer, so expect at least 3 months to get crystals and boards.

Hi Andrea,

Have you carried out any phase noise comparisons using the Old Driscoll XO PCB with 6v supply (sine out before the squarer) against the New Driscoll XO PCB with 12v supply (sine out without squarer) with any of the crystals?
Would be interested to see the delta.

 

[andrea_mori]

I have published the phase noise plot of the old Driscoll oscillator at 11.2896 MHz in post #2092
The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator

 

[Sligolad]

Thanks Andrea, that is a significant improvement. I must go back and catch up on that thread again. Looking forward to getting these new oscillators in my DAC and hopefully later in your DAC

Order Form Summary ?

Hi all,

A while back I proposed to make a Google Spreadsheet for the order summary, so here it is (Order Form Summary) !

It is up to Andrea if he thinks this is a good idea or not. Will wait for his blessing

)) Per

P.S. The spreadsheet is updated, no guarentees, please check yourself. 'ernesternest' was the only one I was not able to understand.

 

[andrea_mori]

Great work, thank you very much, this is a great help to understand how the orders situation is evolving.

You absolutely have my blessing.

I kindly ask all the member to update the spreadsheet with their orders.

I have just updated the first post including the link to the shared spreadsheet.

 

[phi]

You're welcome !

Thougth it would make things a lot simpler to get an idea of the status. The drawback migth be that we draw premature conclusions and don't order what we really want to order based on what we see in the order form summary.
(so don't assume anything, YET ! )

This is a straigth copy of the rows in the original orderform so it should be possible to take copy from that sheet to this one.

Andrea, so I will keep it on my Google Drive or do you want to be in charge?
(Does not really matter to me)

Hi Phi,


I don't succes to fil your on-line form... Does one need a google account ?

Hi Per,
thanks again.

You can keep it on your Google Drive, I have already much confusion to manage the GB documents!

 

[phi]

Hi Phi,


I don't succes to fil your on-line form... Does one need a google account ?

You should be able to Open and Edit without a Google account to my knowledge. I have set sharing options so anyone shall be able to Edit. I thougth this solution was bullet proof

Can you view the File ? See below, does this new info help you ?

Try this link instead !

I did make a copy of Andreas Order form but did not pay enough notice about it beeing saved as an XLSX-file. I have now saved the file as a 'pure' Google Docs Spreadsheet. Sorry for the confusion.

Andrea, could you please update you link in the first post with the new one above ?


)) Per

P.S. You can always create a Google account, takes a minute, but I undestand if you don't want to.

 

[phi]

Andrea, understood. Will be the keeper of this document. We'll see how well it works out.

Phi, thanks for your nice work with the spreadsheet!

I have added a preliminary board TWTMC-SWITCH that Andrea has proposed
if interest is 10 or more. Andrea, please edit description/name etc if something is not correct.

 

[phi]

I have just fixed so the first "Order Form Summary" in Post 731 has a link in the Spreadsheet that links to the new "Order Form Summary" in post 736.
(Wrong format, changed from XLSX to Google Docs)

Hopefully it now works for everyone to edit/update.
