Oscillators: 520L25DA26M0000 Application Field and Working Principle

An oscillator is a circuit that produces a repetitive or periodic output signal. The 520L25DA26M0000 oscillator is a voltage controlled oscillator (VCO) operating at a frequency of 520MHz with low phase noise. It can be used for synthesisers, communication receiver systems, microwave phones, instrumentation telecom, SATCOM, medical imaging systems and military and aerospace applications.

The 520L25DA26M0000 oscillator has a number of features that make it well suited to a variety of applications. It has a low phase noise of -110 dBc/Hz at 100 kHz offset and a very low harmonic distortion of -50 dBc. It also offers wide tuning range, fast start-up time, low power consumption, and solid-state reliability. Furthermore, the device is easy to use and can be programmed through a serial interface.

The 520L25DA26M0000 oscillator works based on the principle of frequency conversion. It consists of an oscillator, frequency divider, and phase-locked loop (PLL). The oscillator is a voltage-controlled crystal oscillator (VCXO) that provides the base frequency signal. The frequency divider divides the base frequency signal into two signals that are 180° out of phase with each other. The PLL then combines these two signals and adjusts the frequency and phase for the output signal based on the voltage input.

The 520L25DA26M0000 oscillator is designed to operate in the range of 520 MHz to 2.5 GHz. The output frequency can be adjusted by adjusting the voltage applied to the control pins. The frequency will typically drift less than 1 pentahertz (10^-15) over a temperature range of -20°C to +90°C. The device is supplied in the industry standard 14-pin flatpack. It is lead-free and RoHS-compliant, making it suitable for commercial and high-reliability applications.

In conclusion, the 520L25DA26M0000 oscillator is a versatile and reliable device for a variety of applications. Its features and specifications make it suitable for use in a wide range of applications, from communications to instrumentation and military/aerospace applications. Its low power consumption, low harmonic distortion, and low phase noise make it an attractive choice for signal processing and communication.
