Oscillators are electrical circuit components capable of producing repetitive signals in a variety of forms, in order to alter or maintain operational parameters. Within this general class, the SIT8208AC-21-28S-19.440000Y is a highly versatile active device featuring a voltage-controlled Frequency Synthesis and a phase-locked loop (PLL) oscillator with low-noise characteristics.

This type of oscillator is very popular in precision timing control and is frequently utilized in electronic spectrometry, radar and digital communications systems, where accurate and reliable frequency control is essential. The SIT8208AC-21-28S-19.440000Y consists of an integrating ramp generator, a voltage-controlled oscillator (VCO), an output buffer and a phase comparator.

The output buffer can provide a voltage swing up to 2.6V with amplitudes greater than 3Vpeak-to-peak. The loop has a high energy efficiency and a wide frequency range. Its dual-mode design allows for the production of both stable and periodic waveforms. The SIT8208AC-21-28S-19.440000Y is capable of producing up to 30MHz of output frequency with 0.25ppm accuracy over the -30 to +85C temperature range.

The integrated phase-locked loop (PLL) enables a better control over the output frequency, and also enables higher frequency generation, greater jitter suppression and improved signal integrity. It has been implemented to reduce the possibility of parameter drift due to temperature effect or capacitance/resistance variation. The VCO section of the SIT8208AC-21-28S-19.440000Y provides a wide tuning range with a low voltage control characteristic, which enables excellent synthesis of signals over a wide frequency range.

The output buffer contributes to generate low distortion, low noise and high linearity. This oscillator also features a very low phase noise, as the PLL circuit eliminates the need for an external loop filter and reduces any possibility of current consumption. The use of advanced process technologies allows for very low noise, low power applications, making the SIT8208AC-21-28S-19.440000Y suitable for applications where sensitive frequency ranges are required.

The low power consumption of the device makes it suitable for portable and battery powered applications, while its high output current makes it ideal for driving RF power amplifiers. The device is extremely reliable in different environmental conditions and can be used in harsh weather conditions. It is also highly stable, and can provide a wide range of modulation schemes for spectral power control.

The SIT8208AC-21-28S-19.440000Y is an important component in many electronic circuits, and its use can dramatically reduce system noise, power consumption and promote better system accuracy and reliability. A variety of circuit designs and applications have been proposed for this device in order to best meet the complex surrounding conditions.
