Oscillators

The DSC1033CC1-050.0000T is a frequency-stabilized VCXO (Voltage Control Crystal Oscillator) in industry standard packages. This component is commonly used in applications for modulating or demodulating audio signals or for clock synchronization. The VCXO is based on frequency control of a quartz crystal and is adjustable over a wide frequency range. It is highly stable and reliable over temperature, time, and voltage.

Applications

The DSC1033CC1-050.0000T can be used in a variety of applications. One of the most common is in modems for DSL: such as ADSL and VDSL. It is also used in ADSL modems used for data transmission and syncing audio signals on consumer electronics. It is also used in a number of industrial and automotive applications, including radio communication and navigation systems.

The Working Principle

The DSC1033CC1-050.0000T works similarly to other VCXO components. A quartz crystal is connected to the oscillator circuit through a control voltage (CV). This CV applies an electric current to the quartz crystal, thus changing its shape and hence its resonant frequency. The DSC1033CC1-050.0000T has a temperature compensated oscillator and can keep its precision in a pre-defined range.

The quartz crystal used in this oscillator contains two metal plates joined together using tiny electrodes. They are held in place by a dielectric material. This arrangement is referred to as a piezoelectric quartz crystal resonator. When an electric current is applied to the quartz, the crystals vibrate at a specific frequency as per their natural resonance. This frequency is determined by their physical properties. The quartz crystal is matched to a specific range and can be adjusted within that range.

The other factor that contributes to the DSC1033CC1-050.0000T frequency stability is the temperature compensation. This is achieved through the use of a thermistor which is connected to the oscillator circuit. As the temperature of the environment changes, the thermistor adjusts the current to the quartz to ensure it remains within the pre-defined frequency range, thus maintaining the frequency stability of the oscillator.

Advantages and Disadvantages

One of the major advantages of the DSC1033CC1-050.0000T is its stability over time and temperature, making it ideal for precision timing applications. It is also more cost-effective than many of its counterparts, making it a great choice for low-cost projects. On the downside, it is limited to a pre-defined frequency range and doesn’t offer any flexibility. It is also more susceptible to vibration than other oscillators.

Conclusion

In conclusion, the DSC1033CC1-050.0000T is a highly reliable and cost-effective oscillator component. It is ideal for precision timing applications and for applications where stability is paramount. However, it is limited to a pre-defined frequency range and should be used with caution if vibration is expected.
