LClock Schematics

And here the photo of the LClock XO from the above schematic.

BRAVO !! BRAVO !!! KEEP'EM COMING KEEP'EM COMING

Lars, just a question, why didn't you just "sniff" the oscillator signal at the emitter and via an emiiter follower (BJT or JFET) feed the signal to the HCMOS gate?

 

[Lars Clausen]

Peranders: As you might have noticed i did that in the first version of LClock 1. However i found that the noise at the xtal directly is lower, so you can get a better performance this way.

That's the one I have.
Maby with some very minor differences.
I think I bought my XO in 1999.

LCAudio?

Look that generator.... For my sense LCAudio - garbage, especialy it cost.

Aaah the old 'I can tell how it sounds and performs by looking at the schematic'.

As for cost, how much does the test equipment to measure phase noise / jitter to these levels cost these days?

[Yuri Birukov]

Are you compare LCAudio and Lynx generators?

Measuring... noise.. jitter... how many words! LCAudio - cheap and noisy circuit technique and ordinary components, look it. LCAudio - standard generator....

Biography school, military service in the KGB, university, hm interesting, especiall the KGB part

Anyway Yuri, what exactly is the garbage?

Looking at your schematics (are you the designer?) how does this design perform in numbers?

Are you discussing my biography or generators?

Circuit technique...

We can only speculate what that means

'Agent triple-x, you must report to headquarters immediately'.. perhaps

I Like that one!

Hi Lars,

If I may call you Lars, I like your kind of humor!

Thanks for posting the XO2 schematic. Nice work

Audiofanatic: You are welcome to call me Lars, i am honored!

Here are the schematics of LClock XO3.

If you attempt to build it, please bear in mind, that full performance level can only be expected if the clock is built on a 4 layer PCB.

The drawing is a bit blurry, but i think you get the idea of the circuit anyway.

Since it is a commercially available product, i will not post a photo of this clock ..

 

[Lars Clausen]

And here a zip with a higher resolution schematic of LClock XO3.

Have fun!

Wow, great of you to publish present design.

 

[tbla]

publish present design.

'Agent triple-x, you must report to headquarters immediately'.. perhaps

Lars, you kinda may be sometimes a good company.

Thanks for the schematics.

Since you are concerned about the supply noise, you might use lower noise opamps than 5532. I’ll not make a problem if I’ll see next year you use this advice for the commercial purposes.

(I saw one supply that, I suppose, has lower noise because it uses lower noise opamps and slightly quieter voltage reference… Elso uses it for his own DAC, ask him for the schematic…)

PS: Would someone say what does mean zavjazijvaj? And what is that font?
