Oscillators are electronic circuits that generate periodic electronic pulses or waves. Since they produce signals of a certain frequency, they are used to create clocks necessary for many digital systems and timing circuits. The CE3291-33.333 is one such oscillator, in particular a high-speed VCO (Voltage-Controlled Oscillator).

CE3291-33.333 Application Field

The CE3291-33.333 oscillator is designed for use in high speed applications such as in digital communication systems and mixed-signal circuits. Due to its high speed operation, it is suitable for use in frequency synthesizers, modems, and high-speed signal processing. Furthermore, it is also suitable for use in analog-to-digital and digital-to-analog conversion. Its wide operating range and low power consumption also make it ideal for radio frequency (RF) applications including VHF and UHF circuits.

CE3291-33.333 Working Principle

At the heart of the CE3291-33.333 sits a ferroelectric crystal, which acts as the frequency-determining element. The crystal’s resonance frequency can be adjusted by applying a voltage to it. This voltage is supplied by an external voltage-controlled oscillator (VCO) circuit which is composed of a comparator, a LC tuned circuit, and an amplifier. This circuit acts as a negative feedback loop, with the comparator receiving a frequency watch signal from the crystal, and varying the operating current to the crystal in response to the frequency change. As the operating current is increased the operating frequency also increases, and vice versa.

The CE3291-33.333 oscillator is an analog oscillator, and its operating frequency can be adjusted continuously with no discrete steps. It also has high stability and low phase noise. The crystal used in the oscillator is highly reliable and temperature compensated, providing added accuracy and stability when operating over a wide range of temperatures.

Conclusion

The CE3291-33.333 is a high speed oscillator designed for use in many applications such as frequency synthesizers, modems, and signal processing. Its low power consumption, wide operating range, and high stability make it a good choice for these applications. Its frequency is determined by a ferroelectric crystal which is adjustable in response to an external voltage, ensuring precise frequency control.
