5. Example
The division-number calculation can be explained with the following example.
1. The desired VCO frequency F
VCO= 850 MHz, the reference frequency Fref = 80 MHz, and the RF prescaler divisor
P = 2 (factory set).
2. The reference-frequency division number R is set to one of the two factory-defined values depending upon the VCO
frequency. R is changed between the two defined values to achieve the best spurious and phase-noise performance.
The user is provided with a list of frequencies in Appendix 1 for which R is to be changed from the default value; in this
case, the default value is 10. For frequencies listed in Appendix 1, it is to be changed to 11.
Therefore, using Equation (1):
For F
vco = 850 MHz with P = 2 and R = 10,
The data format for this example is shown in Appendix 2.
The data must be loaded as per the timing diagram (Figure 4).
Appendix 1: R & D5 versus Frequency (Example)
The following data applies only to the example presented in Section 5, above. Consult your FN3000 documentation
for the R & D5 versus Frequency listing specific to the model you have purchased.
1. Set R = 11 and bit D5 = 1 at address 03h for the following frequency ranges (all frequencies in MHz;
step size = 1 kHz):
807.9 – 808.2
815.9 – 816.2
823.9 – 824.2
831.9 – 832.2
839.9 – 840.2
847.9 – 848.2
855.9 – 856.2
863.9 – 864.2
2. For all other frequencies between 803 MHz and 877 MHz, set R = 10 and bit D5 = 0 at address 03h.
