1/ Yes, my fears were confirmed - OHM4 footprint isn't correct (my mistake), but it possible to mount from bottom side.

2/ Noise plots are similar, I think we see limit of LMS performance but not XO (see pictures here).

Also, I found that for 1850MHz better to use Icp=1.2mA.

Therefore I decide to measure at 1.2mA for both frequencies just to compare.

If Icp dependance of frequency confirmed, then we need lookup table for this also.

So, looks like it has a bit worse far-end noise, but otherwise is
about the same as TCXO we use now, correct?

Btw, was it UmTRX layout incorrect or the OCXO pinout?
