Just saw this mentioned in Circuit Cellar, just wonding if it really
exists, how much they are asking, and if anyone has played with one
yet?

http://www.rfx.co.uk/pdfs/GPS_OCXO_1300_10_module.pdf

It is small enough to incorporate in the external antenna !

Hi

The OCXO probably isn't going to do very well with the outdoor temperature swings…

Raj,

JLT just sent out a press release some days ago on the LC_XO sub 1 inch square GPSDO that is smaller and higher performance than the RFX unit, runs from only 3.3V, and it can be soldered into a 100 mil standard breadboard, and consumes only about 0.5W (RFX unit is probably >> 1W).

Why not.. granted it's easier with large mass and large insulation, but
ultimately, it's all about the closed loop gain of the temperature
control loop.  With small mass, the time lag effects will be small, at
least.

Hi

The rated temperature stability of the OCXO is not "super good". You will
see more frequency shift on it than say the TBolt OCXO, far more than a
DOCXO.

That's not at all saying it's a bad part. For Time Nut duty, I would try to
keep it in a fairly benign ambient situation.
