Programmable Divider Structure

Don’t care.
1. Programmable Divider Calculation Examples
FM, 50 kHz steps (DVS = 1, SNS = *, FMIN selected)
FM RF = 80.0 MHz (IF = –10.7 MHz)
FM VCO = 69.3 MHz
PLL fref = 25 kHz (R0 to R1 = 1, R2 to R3 = 0)
69.3 MHz (FM VCO)
÷
25 kHz (fref)
÷
2 (FMIN: divide-by-two prescaler) = 1386
→
056A (HEX)
SW, 5 kHz steps (DVS = 0, SNS = 1, AMIN high speed side selected)
SW RF = 21.75 MHz (IF = +450 kHz)
SW VCO = 22.20 MHz
PLL fref = 5 kHz (R0 = R2 = 0, R1 = R3 = 1)
22.2 MHz (SW VCO)
÷
5 kHz (fref) = 4440
→
1158 (HEX)
MW, 10 kHz steps (DVS = 0, SNS = 0, AMIN low-speed side selected)
MW RF = 1000 kHz (IF = +450 kHz)
MW VCO = 1450 kHz
PLL fref = 10 kHz (R0 to R2 = 0, R3 = 1)
1450 kHz (MW VCO)
÷
10 kHz (fref) = 145
→
091 (HEX)
