Hi Srdjan.
We do not have register dump. However, Lime GUI project file used in this experiment is attached. You can use GUI File->Open Project option to import it. I see Ichp and Ichp offset currents are different from defaults but these still do not justify 5-12dB worse PN in your reports. You can give it a try though before changing TCXCO.
Test Description:
- DC MAX applied through analogue inputs, DACs off
- TXVGA1 and TXVGA2 at max gain
- Loop filter redesigned for 100kHz loop bandwidth and 40MHz reference
- Icp and Icp offset optimized at 25 deg. Same set up used at all other temperatures
- Cap code and VCO picked up by PLL tune routine
