The working principle of the AX7MAF1-491.5200C oscillator is quite simple. When the oscillator is powered on, a charge pump in the oscillator builds up a valid clock frequency. Then the built-in comparator compares the output signal to an on-chip reference clock signal. If the voltage of the output signal is lower than the reference clock, an adjustment circuit sets the correct voltage in order to sustain the voltage of the output signal. This process is continuously repeated to keep an accurate and consistent output frequency.

The AX7MAF1-491.5200C oscillator is an ideal choice for a variety of electronic applications requiring accurate system and frequency timing. Its low power consumption, small form factor, and good frequency accuracy make it a cost-effective oscillator for a wide range of applications in the consumer, automotive, industrial, and communication markets.
