Oscillators

Oscillators are electronic circuits that produce oscillating electric signals. Oscillators are used in a variety of applications and range in complexity from basic LC circuits to more complex electronic circuits.One such oscillator is the CB3LV-5I-26M0000. This device is a temperature compensated crystal oscillator (TCXO) and is used predominantly in applications which require high frequency, low-noise performance. The TCXO has a low phase-noise output and is operated optimally between -20 to +85 degrees Celsius. The CB3LV-5I-26M0000 has a wide range of applications, but is primarily used in telecommunications and satellite applications, where stable and low-noise signals are paramount. Its superior noise performance ensures that signals, including those used in the military can be transmitted without interference. The device also has low-power applications within the medical sector, and is employed in scanning and imaging processes.The device is built using a quartz crystal, which acts as the heart of the oscillator circuit. The crystal’s resonance frequency is determined by the AT-cut of the quartz crystal, a precise manufacturing technique which results in a comparatively low temperature-coefficient. This ensures that the device is thermally stable and can be used in applications in which two or more TCXOs need to be synchronized, for example in cellular phones or in broadcast systems.The CB3LV-5I-26M0000 features an IEEE Standard 118 package, in which a quartz chip, integrated oscillator circuits, temperature compensation and a phase-lock loop are embedded. This ensures low power consumption and small form factor is achieved, whilst maintaining high performance. The working principle of the TCXO is based on the common Colpitts oscillator circuit. A quartz crystal is connected to the input and output of the oscillator as a resonator and an inductor with a variable capacitor is connected to the amplifier circuit in order to set the feedback amount. It is this combination that produces the oscillations. The oscillator circuit is designed so that the frequency is automatically compensated for changes in temperature utilizing the piezo-electric characteristics of quartz. The temperature compensation is achieved through the use of an integrated thermistor which measures the variations in temperature and then adjusts the voltage depending on temperature fluctuations. The CB3LV-5I-26M0000 is typically powered by 3V and has an operational frequency range of 3.2MHz to 26MHz, making this an ideal alternative to an LF (Low Frequency) oscillator. It is a reliable and cost-effective device which is suitable for many applications, including those requiring high frequency and low-noise performance.
