Oscillators

The 8W-133.330MBD-T is a type of oscillators designed for high-accuracy frequency control applications. It provides very stable frequency accuracy even when environmental conditions such as temperature and supply voltage are changing. The accuracy of this oscillator is within a +/–20ppm range, which is a very high degree of accuracy for applications that require precision timing.

Application Field

The 8W-133.330MBD-T is typically used for precision timing applications, such as frequency synthesis, digital signal processing, and general-purpose timing. It can also be used for timing critical applications such as lithographic mask writers, digital imaging systems, and telecommunications networks. This oscillator has become the oscillator of choice for many industrial, scientific, and medical systems because of its dependability.

Working Principle

The 8W-133.330MBD-T is based on a high-performance voltage-controlled oscillator (VCO) that is configured with a varactor diode and a fixed resistor. The varactor diode varies the frequency of the oscillator, based on the voltage that is applied to it. The frequency is controlled by an onboard digital-to-analog converter (DAC) that is programmed with a custom frequency setpoint. The frequency setpoint is provided by an external microcontroller or other device, such as a signal generator or radio frequency source.

The VCO is also connected to a programmable voltage-controlled capacitor (VCC) that is used to stabilize the frequency by compensating for the external environment. The VCC is programmed with a setpoint that corresponds to the desired frequency of the oscillator. By adjusting the voltage applied to the VCC, the frequency can be precisely controlled even when changes in temperature and supply voltage occur.

Finally, the 8W-133.330MBD-T oscillator may also be equipped with an on-board temperature-compensated crystal oscillator (TCXO) for improved short-term frequency stability. The TCXO provides a temperature-compensated signal that enhances the overall accuracy of the oscillator.

Conclusion

The 8W-133.330MBD-T oscillator is an excellent choice for applications that require very precise frequency control. It offers a high degree of accuracy and stability, even when ambient conditions are in flux. The oscillator is easy to set up and requires minimal external components. Its onboard VCO, VCC, and TCXO provide reliable performance in all environments.
