Table 11: VCO preprogramming range; bits D[4:0] …continued
These bits are also called Dword: It determines the ratio between LO frequency and VCO frequency.
The bits are used for the calibration protocol of the internal VCO.

Table 12: Main divider range; bits N[14:0]
These bits control the ratio between the LO frequency and the comparison frequency.
N[14:0]
Ratio
Binary value
The ratio N is equal to N14 × 2¹⁴ + N13 × 2¹³ + ...N1 × 2¹ + N0
Table 13: Selects manual or automatic LC oscillator calibration; bit CALMANUAL
This bit controls the LC VCO frequency programming mode.
CALMANUAL
Action
0
automatic process control; the LC VCO searches the better ratio of the
Dword to have the optimum tuning frequency
1
manual process control; the LC VCO is tuned by selecting the
programmed Dword
