the characteristics of using crystal or the mounting condition, they may not oscillate normally. Please evaluate the oscillation start-up characteris-
tics adequately with your actual device. When this device is used for buffer application, please pay attention to input amplitude to the XT pin. If it’s
low input amplitude, the SM5024 series may not operate normally.
