Guido Tent offers a VHQ PLL reclocking PCB with extremely
low jitter rejection corner frequency and a very low jitter
VCXO. I believe this should be far superior to any chip based
solution available.

He is around here somewhere.... Guido??

Cheers,

Terry

Hi,
I cannot use PCB in my project. I need a PLL itself.

Hi

I am around.....

I designed a PLL that uses very ow corner frequency and lowjitter VCXO and low noise power supplies

It is intended to upgrade DACs, where clocks have jitter from 200ps to 1 ns. My unit cleans it up to 8ps

I can send you seperate information if you like

best regards

Default Vcxo

Hi Guido.
Can this VCXO be made with discrette components?? I mean with diodes /varicap??/ and a crystal. It should be possible. I suppose you have tried this method. What are the results??
The vcxo modules are very hard to find /here/. Does farnell sell them??
The other metod is using the not-liked-by-everybody ASRC like AD1896....... But this is a different design.

Hi

Yes you can build a VCXO yourself, but I also sell canned modules, with or without PLL circuit (called XO DAC).

I have built discrete VCXO's but prefer canned modules as these are less sensitive to external disturbance.
