Structure of the Main PLL Programmable Divider
Sample Main Programmable Divider Divisor Calculations
For FM with a step size of 50 kHz (DVS = 1, SNS = *: FMINa selected)
FM RF = 90.0 MHz (IF = +10.7 MHz)
FM VCO = 100.7 MHz
Main PLL fref = 25 kHz (R0 = 1, R1 = 1, R2 = 0, R3 = 0)
100.7 MHz (FM VCO)
÷ 25 kHz (fref) ÷ 2 (for the FMIN 1/2 prescaler) = 2014 → 07DE (hexadecimal)

For SW with a step size of 5 kHz (DVS = 0, SNS = 1: AMIN high-speed operation selected)
SW RF = 21.75 MHz (IF = +450 kHz)
SW VCO = 22.20 MHz
Main PLL fref = 5 kHz (R0 = 0, R1 = 1, R2 = 0, R3 = 1)
22.2 MHz (SW VCO)
÷ 5 kHz (fref) = 4440 → 1158 (hexadecimal)
For MW with a step size of 10 kHz (DVS = 0, SNS = 0: AMIN low-speed operation selected)
MW RF = 1000 kHz (IF = +450 kHz)
WM VCO = 1450 kHz
Main PLL fref = 10 kHz (R0 = 0, R2 = 0, R3 = 1)
1450 kHz (MW VCO)
÷ 10 kHz (fref) = 145 → 091 (hexadecimal)
