MicroSemi is the manufacturer - Find a distributor and order it.

For instance, Digikey has the CSAC ($5312.50) and the eval board ($928.75)

portable isn't a problem - just run it off batteries.

It's pretty easy to hook up - power, 1pps in and out and 10 MHz out 
(they have versions that put out 5, 10.24, and 16.384 MHz too).

A serial port to control the device

The eval board has SMA connectors, a sub-d for the serial port, and 
comes with a wall wart to run it.

Download the Microsemi CSAC UserGuide for more info

you can fool with the disciplining algorithm, etc.
It's a low power device compared to a OCXO (<120mW)

They're a pretty nifty device, even if the price more than tripled in 
the last couple years.


Jackson Labs makes some integrated systems using CSAC, I believe.
