4. AC Characteristics
*1: The frequency fluction ratio indicates the maximum fluctuation ratio from the set center frequency while locked
Because the PLL frequency fluctuates around the set frequency with a certain cycle [approximately CLK (1 CYC
to 50 CYC)], the worst value is not maintained for long. (The pulse, if featured with the long period, would produce
practically no error.)
*2: The duty ratio should be in the range 30% to 70%.
