The frequency synthesizer consists of a voltage-
controlled   oscillator   (VCO),   crystal   oscillator,
prescaler, programmable frequency dividers, phase-
detector and charge pumps. Two different types of
prescalers are integrated, a pulse swallow and a
phase select prescaler. The recommended prescaler
is the phase select prescaler (Prescaler_Sel=0,
which is default). There is both a configurable on-
chip loop filter and an external loop filter. The
lengths of the N and M and A registers are 12, 12
and 6 bits respectively. The M, N and A values can
be calculated from the formula:

    4: RF frequency 430-490 MHz,
Freq_Band[1:0]=1
    2: RF frequency 860-980 MHz,
Freq_Band[1:0]=2-3
 
There are two sets of each of the divide factors (i.e.
A0 and A1). If modulation by using the dividers is
selected Modulation1=1, Modulation0=0), the two
sets   should   be   programmed   to   give   two   RF
frequencies, separated by two times the specified
single sided frequency deviation. For all other
modulation methods, the 0-set will be used. The
value of A is constrained to be less or equal to N,
0<=A<=N.
