AC Characteristics
(1) Clock Timings
(VCC
= 5.0 V ± 10%, VSS = AVSS = 0.0 V, TA = 40 °C to +85 °C)
*1 : The frequency fluctuation rate is the maximum deviation rate of the preset center frequency when the multiplied
PLL signal is locked.
*2 : Internal operating clock frequency must not be over 16 MHz.
