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

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

Table 11:

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.
