Hi
Not quite sure what the units on “expensive” should be in the case of an
Rb standard. We get used to surplus prices on a lot of stuff and that
can skew the “calibration” a bit.
Sell price on a Telecom Rb depends more than a little on how many
you are buying. In modest quantities (100’s at a time) they rarely get
below $1,000.
Even after a number of years on the market, the CSAC still is a unique
part. I’ve had other parts of a similar size on the bench, they aren’t on
the market yet. Those units didn’t hit CSAC power levels. There are other
parts talked about here and there, but none on the market …
I’d say they are fairly priced for what they are.

Interesting project. Would a CSAC actually fit?
Last I heard these are ridiculously expen$ive (£1000+) assuming you can get one.
They are also restricted in some countries it seems.
CSACs are more like $4000 - they were $1000-1500 originally, but post
Microsemi the price has gone up (for any of a number of possible reasons)
There really aren't a lot of other devices with that performance and
that low power. You can get close with some small OCXOs, but in terms of
long term stability, the CSAC beats them, especially in terms of
"frequency accuracy, 60 seconds after applying power"
