Oscillators are electronic circuits that generate an invaluable signal of a continuous, fixed frequency. These signals are commonly used in communication systems and serve as the basis of relatively complex signal formats. This article will discuss the 353SB3C260T oscillator and its associated application field and working principle.

Application Field

The 353SB3C260T oscillator is a piezo-electric crystal oscillator designed for transmitting and receiving applications. With a maximum frequency of 260 MHz, it is well suited for applications that require a controlled frequency of operation. This includes cellular and wireless communications, point-to-point radio, radar, GPS and navigation systems, digital television, satellite broadcast, WLAN and WiMAX systems, and precise time and frequency applications.

The 353SB3C260T oscillator is ideal for use in applications with strict requirements regarding phase noise, temperature stability, vibration tolerance, and frequency stability. It has very low levels of frequency drift over wide temperature ranges, making it suitable for use in multi-channel systems that require simultaneous and consistent signal transmission and reception. Such applications require high level of control over signal transmission and reception, making the 353SB3C260T oscillator the preferred choice.

Working Principle

The 353SB3C260T oscillator works on a piezo-electric process in which a quartz crystal is used to produce a controlled frequency signal. Under the applied electric field, the quartz crystal vibrates at its inherent frequency which can then be amplified as a sine wave. The oscillator utilizes external circuitry for tuning, amplifying and buffering the signal to drive the output stage.

The operating principle of the oscillator is based on the concepts of resonance and self-oscillation. The crystal generates a harmonic output signal based on its resonance with the applied electric field. The microprocessor then uses this signal to control the piezo-electric transducer, allowing it to control the frequency of the oscillator. This allows for accurate tuning of the oscillator, which leads to the desired output signal.

The primary advantage of the piezo-electric crystal oscillator is its wide range of operating temperatures and excellent stability. The quartz crystal is designed to have a very low coefficient of temperature variation so that it can be used in varying ambient conditions. The temperature range over which the oscillator will operate is typically -55 to +125 degrees Celsius, allowing it to be used in a wide range of applications.

The oscillator also exhibits excellent frequency stability. This is due to the fact that the quartz crystal exhibits an extremely accurate resonant frequency over a wide range of temperatures, which leads to a high degree of frequency accuracy at any given temperature. The oscillator is also inherently immune to vibration or shock, which leads to a similarly high degree of frequency accuracy.

Conclusion

The 353SB3C260T oscillator is an invaluable component for use in both transmitting and receiving applications. Its wide range of operating temperatures and excellent frequency stability make it ideal for use in applications that require precise signal transmission and reception. With a maximum frequency of 260 MHz, it is also well suited for applications that demand high signal resolution and accuracy.
