Programmable oscillators, also known as PLLs (Phase Lock Loop), are widely used in the modern electronics industry for a variety of applications including frequency synthesis. One type of programmable oscillator is the SIT3809AI-D-28NE, which is designed for high-performance, high-reliability frequency control. This oscillator is used in electronic systems such as DC-DC converters, programmable logic controllers (PLCs) and removable media drives. This article will discuss the application field and working principle of the SIT3809AI-D-28NE oscillator.The SIT3809AI-D-28NE is a direct PLL (DPLL) based programmable oscillator that operates in the range of 10 kHz to 200 MHz. It offers many performance features including low noise (below 0.9ps RMS), extremely low jitter (below 0.4ps RMS) and a wide frequency range (10 kHz -200 MHz). The device is also capable of multiple frequency control modes, including one that allows for direct digital Synthesis (DDS). This is ideal for systems that require precise waveform control and are frequently used in audio and video systems. In addition to its high performance, the SIT3809AI-D-28NE is also very reliable. It has been designed to operate in high-temperature environments and is rated for up to 125 degrees Celsius. It also has a robust power protection feature which ensures the oscillator will be able to remain in operation even if power is momentarily lost.The working principle of the SIT3809AI-D-28NE oscillator is based on the operation of a phase-locked loop (PLL). This is a control system that relies on feedback to maintain a constant phase relationship between two signals. In the SIT3809AI-D-28NE, the oscillator is the feedback circuit, and the phase relationship is maintained by a voltage controlled oscillator (VCO). The VCO produces an output signal that is phase-shifted from the input signal by an amount determined by the control voltage. The SIT3809AI-D-28NE utilizes this principle to generate an output signal with a frequency that is controlled by an external voltage. This device can be configured to generate a single frequency, or multiple frequencies, depending on the application. The VCO is adjustable and can be tuned across a wide frequency range to accommodate various applications.The SIT3809AI-D-28NE is a versatile programmable oscillator that can be used in a variety of applications, including radio frequency (RF) systems, audio and video systems, and instrumentation equipment. It can also be used in systems that require precise frequency control, such as those found in motor control and robotics. With its high performance, reliability and a wide range of frequency control modes, the SIT3809AI-D-28NE is an ideal solution for applications requiring a reliable, high-performance oscillator.
