possibly it's 20 years of aging at 40 degrees within the spec.

I just looked at the data sheet. It says:
Frequency Pulling: ±20ppm APR Min.
I was going to ask what APR meant. In case anybody else is also curious...
The CVS575-500 data sheet
their CVS575-500. Nice, bit pricier though...

Hi Fred,
I like the Crystek CVHD parts, and MtronPTI also has a number of good ones.

Thanks Said,
My object of the exercise was to multiply the error of a 10Mhz Rb /GPSDO source
so that I would get 8x phase error between two compared frequencies.
This I presume would make adjustments of my sources much easier.
OTOH, if we lock 80Mhz to Rb source and use that as a clock for the S

Hello Raj,
our ULN-1100 and ULN-2550 GPSDO's use a 100MHz VCXO locked to the 10MHz
OCXO via an ADF4002 PLL with less than 40Hz bandwidth. After careful
optimization of the layout and the loop filter, the phase noise results are
quite
excellent at 100MHz, see the attached plot. The plot s
