Value
*1: The frequency fluction ratio indicates the maximum fluctuation ratio from the set center frequency while locked
when using the PLL multiplier.
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%.
