Oscillators

An oscillator is an electrical device that produces a periodic and repetitive waveform. MX553DBG166M666 is a reliable, voltage-controlled crystal oscillator (VCXO), designed for frequency control in applications such as Telecommunications, Networking & Data Communications, Wireless Communications and Global Positioning System (GPS).

Application Field

MX553DBG166M666 is a highly integrated and versatile device. It can be used in a wide range of applications, including clock and frequency control, frequency synthesis, signal conditioning, phase-locked-loop (PLL) based frequency synthesizers, and burst-mode electrical tuning.

It also has optimal performance in multiple industrial, automotive, medical, military, and aerospace applications. These applications need fast and accurate measurements over a wide range of temperatures. This oscillator is specifically designed for size- and cost-sensitive designs, providing an optimal combination of excellent temperature stability, low jitter, and high frequency accuracy.

Working Principle

MX553DBG166M666 is based on a piezoelectric quartz-crystal resonator. The quartz resonator is connected to an amplifier, which is used to monitor the frequency of the Quartz resonance. A voltage-controlled oscillator (VCO) is used to amplify the quartz’s frequency to produce the output signal. The VCO controls the output frequency by the supplied voltage. The oscillator is able to function in either Temp-compensated mode or Frequency-modulated (FM) mode.

In Temp-compensated mode, the frequencies of the output signal is temperature compensated. This mode is used when temperature stability in the crystal oscillator is more important. The FM mode is preferred in applications where the frequency of the oscillator varies significantly.

The output signal is provided as a high and low level signal. The high level signal socket supplies the output, while the low level is used for selecting the frequency. This allows the oscillator to have better stability over temperature changes and provide higher accuracy.

Conclusion

In conclusion, MX553DBG166M666 is a reliable and versatile voltage-controlled crystal oscillator. It can be used in multiple applications, including frequency control, frequency synthesis, and signal conditioning. It has excellent Temp-compensated mode and Frequency-modulated (FM) mode, which can be used according to the needs of the application. It has good temperature stability and high frequency accuracy, making it an ideal choice for size- and cost-sensitive designs.
