Oscillators

An oscillator is an electronic circuit that generates a periodic, oscillating electrical signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many different applications from electronic test equipment and digital audio to radio and television receivers. This article focuses on the TA-76.800MBE-T oscillator and its application field and working principle.

Application Field

The TA-76.800MBE-T is a high-performance frequency control product that is applicable to a variety of applications such as telecommunications, automotive electronics, power electronics, consumer electronics, digital products and precision electronic components. It is a temperature compensated crystal oscillator (TCXO) and its small size (width of 5.0mm) and excellent performance make it an ideal solution for applications where a reliable and accurate frequency control is necessary.

The TA-76.800MBE-T TCXO is designed to generate a sinusoidal output signal with a frequency range between 0.2MHz and 100MHz, with an output level of 3.3V. It is able to operate up to 15MHz with a supply voltage between 3.0V and 3.3V, and up to 40MHz with a supply voltage between 2.5V and 3.0V. The low jitter and low phase noise performance makes it an ideal solution for precision timing applications.

Working Principle

The TA-76.800MBE-T TCXO operates by using a quartz crystal as the signal source. The quartz crystal is placed in a high quality oscillator circuit, which is designed to generate a sinusoidal AC waveform. This waveform is then fed into a voltage-controlled oscillator (VCO) or a phase-locked loop (PLL) for further frequency modulation and precision timing purposes.

The TCXO is an oscillator that uses a temperature-controlled environment to provide frequency stability. This environment ensures that the oscillator\'s output frequency remains stable over a relatively wide temperature range (available with ±2.5ppm, or ±0.3ppm stability). The temperature compensation works by a negative temperature coefficient (NTC). The NTC uses a thermistor to measure the ambient temperature and to adjust the frequency accordingly.

The TCXO also features an adjustable output frequency, allowing for precise frequency adjustment on the final product. This is achieved by using an external voltage-controlled capacitor (VCC), which is used to adjust the frequency at the required level. The frequency can be set on the fly, without requiring any external components. This feature makes the TCXO ideal for frequency precision and control applications.

Conclusion

The TA-76.800MBE-T TCXO is a high-performance frequency control product designed for a variety of applications. It features excellent performance and low jitter and low phase noise, making it ideal for precision timing applications. The adjustable output frequency enables precise frequency adjustment, and the temperature compensation ensures stability over a wide temperature range. The small size of the device makes it suitable for many different applications.
