t(SXO)

Start-up time(3)

TA = –25 °C to 85 °C

(1)

The frequency error is measured from 4.194 MHz.

(2)

The frequency drift is included and measured from the trimmed frequency at VREG25 = 2.5 V, TA = 25°C.

(3)

The startup time is defined as the time it takes for the oscillator output frequency to be ±3% when the device is already powered.
