Andrey Sviyazov andreysviyaz at gmail.com1/ 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.
