An oscillator is a device or system that generates a periodic, oscillating signal, the frequency of the oscillation depending on the components of the system and its operating environment. SIT9002AC-083N33EO156.25000T is one of these oscillators.

Application Field

SIT9002AC-083N33EO156.25000T is mainly used in UHF (Ultra-High Frequency) timing applications. It is designed for use in broadcast and cable TV, CATV and other related systems where tight frequency control is required. Its frequency range is from 15 MHz to 156.25 MHz, making it well-suited for applications where a wide frequency range is needed.

Working Principle

The SIT9002AC-083N33EO156.25000T consists of two main components: a voltage-controlled oscillator (VCO) and a frequency control system. The VCO is the heart of the oscillator circuitry and consists of an amplifier and an active element. It is driven by a voltage source which can be adjusted to control the output frequency. The frequency control system is composed of adjusted capacitors and variable inductors, which are used to precisely tune the output frequency. The frequency control system also contains logic circuits and counters, which are used to provide an interface for controlling the oscillator frequency.

The SIT9002AC-083N33EO156.25000T also includes a temperature-compensated system, which ensures that the output frequency is highly stable over varying temperatures. This temperature compensation system adjusts the capacitance of the active element to maintain the frequency accuracy of the output waveform over a wide temperature range.

The SIT9002AC-083N33EO156.25000T is capable of producing a sinusoidal output waveform or an output pulse waveform. It can also be programmed to select either manual or automatic frequency control. In addition, it contains a low phase noise circuit, which considerably reduces the noise levels associated with its operation.

Conclusion

The SIT9002AC-083N33EO156.25000T is a versatile oscillator that is used in a wide range of applications from UHF timing applications to broadcast and cable TV systems. Its frequency range and temperature compensation system make it well-suited for these applications. Further, its low phase noise circuit helps to minimize the noise associated with its operation.
