1)
The minimum total divide ratio is only important for continuous frequency step size, if lower divide ratios
are used not all frequencies are possible. To find out the missing frequencies our Windows control
program for I
2
C / 3-wire bus may be used.
2)
Step sizes > 2 MHz are not guaranteed, 1 MHz continuous step size is only possible for RFin > 992 MHz
3)
For low power dissipation the use of the 64/65 prescaler should be preferred if the desired step size fits
