The Well Tempered Master Clock – Building a low phase noise crystal oscilllator

[The Well AudioParticipant]

Since the original thread on diyaudio.com has been closed the topic is renewed here.

This topic is about low phase noise/jitter oscillator to be used in digital to analog conversion.

I just want to order the next batch of parts for my upcoming Drixo-clocks and figured that the B82132A5401M000 is end of life and no stock anymore at Mouser…is there n alternative ? Digikey still has a stock, but I dont have enough stuff from them to order…alternatives only if there is no sound quality degration…otherwise I will just make up an order somehow from Digi…

You can replace the part with the EPCOS B82111E0000C024 (Mouser part 871-B82111EC24).
It’s a little wider but it should fit.

Andrea, I was about to put together DRIXO but notice the chokes I have do not match the current BOM

 

Mine:
B82132A5401M000
B82132A5301M000

BOM:
B82111E0000C026
B82111E0000C024

When I  upload the BOM to mouser it to shows upper one , but viewing BOM in spreadsheet shows the lower one.

Which is correct?

If it is the lower part I wonder if anyone else had this error and is possibly using the wrong part in their XO.

These inductors have been replaced in the BOM because they are obsolete.
They are both correct, old and new parts.

Andrea,

A question on the TWTMC-PPG-V2. I see the board is set up to accept 6.6 Volts as the power input. I’m presuming that’s intended for a pair of Lithium Batteries. True?

What’s the maximum and minimum voltage for avoiding damage and good performance?

Thanks,

Hugh

Allowed power supply voltage is 5V up to 7V.
Best phase noise performance are reached with 6V6.
