Working Principle of M685-02-AA-AH: The oscillator consists of a simple quartz crystal, an amplifier, a divider and a reference source. The quartz crystal serves as an oscillator, providing an alternating electrical waveform. The amplifier amplifies the electrical waveform and feeds it back to the quartz crystal for further amplification. The waveform produced by the quartz crystal then passes through a divider, which divides it into two streams. The two streams are fed to the reference source, where they oscillate and generate signals with a fixed frequency. The frequency of oscillation is determined by the reference source. The signals are then fed back to the control pins, which can be used to synchronize the oscillator with external logic devices or to change the frequency.

In conclusion, M685-02-AA-AH oscillator is a type of pin configurable and selectable oscillator, which is widely used for frequency changes in various applications. It features a variety of package sizes, many mounting styles and frequency range from 1 MHz to 700 MHz. Furthermore, its stability is ±10 ppm, which ensures good accuracy.
