Working Principles

The SIT9120AC-2C1-25E166.666000T oscillator is based on the EDMO-VCO (Electric Discharge Machined Oscillator-Voltage Controlled Oscillator) oscillator architecture, which combines several components into a single package. At its core is an inductor which serves as the oscillator\'s primary frequency-determining element. The EDMO-VCO architecture also includes two electronic varactors, resistors, and capacitors to provide frequency control and internally trimmed fine-tuning.

The oscillator\'s output signal is phase-modulated by the frequency control voltage. This voltage is derived from the internal varactors, which act on a circuit\'s input impedance to change the circuit\'s frequency. The SIT9120AC-2C1-25E166.666000T oscillator works on the principle of phase locking, which provides high stability over its range of operating temperature.

The oscillator also has an Integrated Frequency Discriminator (IFD), which helps to protect the oscillator from ambient noise. The IFD automatically adjusts the oscillator\'s output frequency in order to maintain its accuracy in the presence of interference. The IFD also helps to reduce spurious signals generated by the oscillator.

The SIT9120AC-2C1-25E166.666000T oscillator is capable of withstanding extreme temperatures, ranging from -40°C to 85°C, and is rated for up to 10 years of uninterrupted operation. It is also capable of operating over a wide frequency range, from 0.5MHz to 400MHz, and has excellent shock and vibration resistance.

The SIT9120AC-2C1-25E166.666000T oscillator offers outstanding performance in a low-cost, small package. It is an ideal choice for applications that require precise timing and frequency control in harsh environmental conditions.
