(1)
The frequency error is measured from 4.194 MHz.
(2)
The frequency drift is included and measured from the trimmed frequency at VCC = 2.5 V, TA = 25°C.
(3)
The start-up time is defined as the time it takes for the oscillator output frequency to be within 1 % of the specified frequency.
(4)
The frequency error is measured from 32.768 kHz.
(5)
The start-up time is defined as the time it takes for the oscillator output frequency to be ± 3%.
