Design and Theoretical Working Principle

The AX7PBF4-77.7600T is a quartz crystal oscillator, which is a type of electronic oscillator that uses an integrated circuit powered by a quartz crystal to generate electrical signals. The quartz crystal provides an external source of electrical stability, which enables the oscillator to produce a reliable output frequency. The output frequency of the oscillator is determined by the resonant frequency of the quartz crystal, which can be varied by changing the circuit components. The AX7PBF4-77.7600T consists of an integration of the quartz crystal, frequency control components, a DC voltage source and an output control circuit.

The quartz crystal is an inductor and a capacitor in series. Inside the oscillator, a quartz crystal is connected to the circuit by a pair of electrodes. The quartz crystal acts as an electrical oscillator, with the counterbalancing of the inductance and capacitance causing the oscillator to vibrate at its natural resonant frequency. The oscillator circuit also contains a capacitor and an inductor in series with the quartz. The capacitor and inductor both provide electrical stability, ensuring that the output frequency remains constant even when environmental conditions change.

The frequency control components of the AX7PBF4-77.7600T oscillator are made up of a transformer, a multilayer integrated circuit (MLIC) and various other discrete components. The MLIC contains control logic that is responsible for adjusting the output frequency of the oscillator, as well as controlling its amplitude and phase. The transformer is used to allow the power supply voltage and frequency to be varied, while the discrete components enable fine tuning of the frequency characteristics.

The output control circuit is responsible for creating an output signal from the oscillator. This circuit consists of a power amplifier, a buffer and a capacitor that control the voltage of the output signal. The output frequency is determined by the frequency of the quartz crystal and can be changed by adjusting the control logic of the MLIC or by changing the frequency of the power supply.
