Initial Value: FC = 1016 (Two's complement format)

Must set the FC value between -1516 to +1515.

Example1)

VCO frequency "fvco" is set as follows.

fvco = (NC+53) x fosc + FC x fstep

fvco: VCO Frequency

fosc: Reference Clock Frequency (30.32MHz)

fstep: Frequency Step (= fosc / 3032)

fvco = 1890MHz / fosc = 30.32MHz / fstep = 10kHz (= 3032 / 30.32MHz)

NC = fvco / fosc - 53 = 1890MHz / 30.32MHz - 53 = 9.335

NC = 9 (This number is rounded to an integer.)

FC = (fvco / fosc - (NC+53)) x fosc / fstep = (1890MHz / 30.32MHz - (9+53)) x 30.32MHz / 10kHz = 1016

NC = 9

NC = “b’1001” (Binary)

FC = 1016

FC = “b’001111111000” (Two's complement format)

Example2)

RX frequency "frx" and TX frequency "ftx" are set as follows.

frx = (fvco / nd) - f_if = [(NC+53) x fosc + FC x fstep] / nd - f_if

ftx = fvco/ nd = [(NC+53) x fosc + FC x fstep] / nd

frx: RX frequency

ftx: TX frequency

f_if: IF frequency (230 or 280 kHz)

nd: Division Ratio (nd = 6 at 315MHz Band, nd = 4 at 434MHz Band, nd = 2 at 868 / 915MHz Band)

frx = 314.94MHz / fosc = 30.32MHz / fstep = 10kHz (= 3032 / 30.32MHz) / f_if = 280kHz

In this case, nd = 6, as frequency band is 315MHz.

Actually to calculate frx, firstly calculate fvco based on frx, next determine the number of NC and FC.

fvco = (frx - f_if) x nd = (314.94MHz - 0.28MHz) x 6 = 1887.96MHz

NC = fvco / fosc - 53 = 1887.96MHz / 30.32MHz - 53 = 9.268

NC=9 (This number is rounded to an integer.)

FC = (fvco / fosc - (NC+53)) x fosc / fstep = (1887.96MHz / 30.32MHz - (9 + 53)) x 30.32MHz / 10kHz = 812

NC = 9

NC =“b’1001” (Binary)

FC = 812

FC =“b’00110010110” (Two's complement format)

By using those NC and FC, fvco and frx can be calculated again.

fvco = (NC+53) x fosc + FC x fstep = (9 + 53) x 30.32MHz + 812 x 10kHz = 1887.96MHz

frx = (fvco / nd) + f_if = (1887.96MHz / 6) + 280kHz = 314.94MHz
