s FUNCTIONAL DESCRIPTIONS
<A type>
Divide ratios of the internal counters can be set optionally according to customer requirements. Two different
frequencies can be selected by Div input ”H” or ”L”.
The divide ratio can be calculated using the following equation:
fVCO = {(P x N) + A} x fOSC ÷ R (A < N)
fVCO: Output frequency of external voltage controlled ocillator (VCO: up to 500 MHz)
P: Preset divide ratio of dual modulus prescaler (8/9, 16/17, 32/33)
N: Divide ratio of the main counter (5 to 4,095)
A: Divide ratio of the swallow counter (0 to 31)
fOSC: Reference oscillation frequency ( up to 26 MHz)
R: Divide ratio of the reference counter (5 to 4,095)
