Working Principle

The working principle of the ASTMHTD-66.666MHZ-AK-E oscillator is relatively simple. It is based on the principle of frequency-modulated (FM) oscillation, which is a type of oscillation generated by changes in the frequency of a signal. The oscillator consists of two transistors that are connected in a complementary-symmetry arrangement, with one transistor acting as the emitter and the other as the collector. The resulting signal is then multiplied in frequency by the internal circuit, allowing the output frequency to be controlled using an externally applied voltage.The ASTMHTD-66.666MHZ-AK-E oscillator also utilizes a voltage-controlled-oscillator (VCO) circuit for frequency control. This VCO circuit consists of a capacitance diode and a transistor, which are connected in a classic negative-resistance oscillator configuration. This configuration is able to provide frequency adjustment and signal linearity over a wide range of input voltages.The ASTMHTD-66.666MHZ-AK-E oscillator also has a reference crystal, which is essential for achieving superior frequency stability and phase noise performance. The crystal is connected to the oscillator’s output in order to control its frequency, which is then fine-tuned using the VCO circuit for precise frequency setting.
