Default reclockers UNITE! Valpey-fisher extreme XO may be available...

I have found a potential source for an extreme XO with the following specs:

Frequency 11.2896 MHz
Temperature stability <10 ppm to 70C
Phase noise -155 dBc/Hz on the floor
Phase jitter < 0.2 ps RMS from 100 Hz to 10 MHz jitter frequency
Power supply 5V (optional 3.3V)
Package 4 pin DIP (VTL140)

These specs are 3 orders of magnitude better than the clock recovered on crystal's receivers (8412, 8414)! 1000x less jitter across a wide frequency spectrum? This is an awesome XO.

What's more, the cost is $30 per piece with an order of 100 or more. It might be $60 or so for a smaller order, I'm not sure about that yet.

Let me know if you're interested.

Do a search under sound of xos and look for my name. They were the top spec VF150 8 pin with the same spec as VF140.

You have to compare apples to apples. The XO I got quoted has the following spec:

Phase jitter < 0.2 ps RMS from 100 Hz to 10 MHz jitter frequency
Whereas the 150 you got a quote on was <1 ps RMS @ 1000 Hz

The 140 is a fully sweep-tested XO with jitter levels 1/5 that of the 150 you mentioned...

I stand by it - this is one of the best XOs that can be had at the price, hands down.

Let me know if you want some everybody....

Sure im in... But you should either enable your email or set up a wiki ...

I think 100pcs is probobly a bit optimistic though...

Is there a complete datasheet on this oscillator somewhere? A quick search on Valpey-fisher did not reveal any.

Why all the brouhaha? When I want a V-F oscillator, I call their distributor and order some. It's not magic.

Hi jwb, Seems then like you are the ideal person to organise the groupbuy......
The problem is I think that standard CD frequencies (11.2896; 16.9344; 45.1584MHz f.a.) are not standard in stock for companies like Valpey-Fisher. Been there done that, well eventually I did order nothing......
