Oscillators: CFL-A7BP-212.5TS Application Field and Working Principle

Oscillators are electronic circuits that generate a repetitive signal in a form of a waveform, most commonly a sine wave. Their main purpose is to generate signals that are used to produce electrical waves of a specific frequency. Oscillators can also be employed in various other applications, such as frequency synthesis, signal conditioning, audio synthesis, and so on.One such a device belonging to the class of oscillators is the CFL-A7BP-212.5TS. It is a high-accuracy crystal- and LC-controlled oscillator incorporating an internal oscillator with a frequency of 10 to 50 MHz. The CFL-A7BP-212.5TS was developed for applications which require a high degree of accuracy, such as adjustable frequency synthesizers, instrumentation control systems, cellular radios, communication satellites, and navigation systems.This particular oscillator is quite versatile, since it can be used for both narrowband and wideband frequency synthesis. The device includes an integrated amplifier and switched capacitor filter which allow for the adjustment of the frequency by as much as three octaves. In addition, the output signal is adjustable between logic- and sinewave standards.One of the main advantages of the CFL-A7BP-212.5TS is its relatively low noise level. The device is capable of operating noise-free at frequencies of up to 15 MHz, and offers phase noise levels of less than -1 dB at any frequency.The working principle of the CFL-A7BP-212.5TS revolves around a quartz crystal, two variable capacitors, and two inductors. The crystal, inductors and capacitors are connected in an LC oscillator circuit, with the output of the oscillator connected to an amplifier. The amplifier then provides the amplified signal to the filter. The filter\'s capacitors act as the switching element, allowing for the adjustment of the frequency. The output of the filter is then connected to the output of the oscillator, which is adjustable between logic- and sinewave standards.In conclusion, the CFL-A7BP-212.5TS is a high-accuracy, crystal- and LC-controlled oscillator designed to operate at frequencies of 10 to 50 MHz. It is suitable for applications such as adjustable frequency synthesizers, instrumentation control systems, cellular radios, navigation systems, and communication satellites. The device offers relatively low noise levels and adjustable frequency capabilities, and is capable of operating with either logic- or sinewave output signal levels.
