Notes:
8.
B is greater than or equal to A.
9.
Divide ratio less than 3 is prohibited. The divide ratio can be calculated using the following equation:
10. Operating temperature range: –40°C to +85°C.
fvco = {(P * B) + A} * fosc / R where (A < B)
fvco: Output frequency of the external VCO.
The divide ratio N = (P * B) + A.
R: Preset ratio of the 15-bit programmable reference counter (3 to 32767).
fosc: The crystal reference oscillator frequency.
A: Preset divide ratio of the 7-bit swallow counter (0 to 127).
B: Preset ratio of the 11-bit programmable counter (3 to 2047).
P: Preset divide ratio of the dual modulus prescaler (64/65 or 128/129).
