Value
* : The frequency fluctuation rate is the maximum deviation rate of the preset center frequency when the multiplied
PLL signal is locked.
The PLL frequency deviation changes periodically from the preset frequency “(about CLK
×
(1CYC to 50 CYC)”,
thus minimizing the chance of worst values to be repeated (errors are minimal and negligible for pulses with
long intervals).
