Frequency synthesizer startup cc1101

[Alex A. (alextbg)]

Hello there,
I want to program the cc1101 chip. The problem is, that I don't know 
what the "Frequency synthesizer startup" is. It is named in the 
datasheet but I can't find any further information about it. Thanks for 
helping and a good new year

The only reference to "frequency synthesizer startup" I can find in the 
datasheet is in Figure 13, which is a state diagram that depicts the 
transitions between the various states the device can be in. There is a 
state labeled "Frequency synthesizer startup, optional calibration, 
settling", which simply appears to be the starting up, calibration and 
settling of the synthesizer.

This is also explained by the text right next to the respective node in 
the diagram, which reads "Frequency synthesizer is turned on, can 
optionally be calibrated, and then settles to the correct frequency. 
Transitional state. Typ. current consumption: 8.4mA."
