Oscillators output an electrical signal with a periodic waveform, such as a sine wave, square wave, or triangle wave. The most common types are those based on the phase-locked loop (PLL) or its variants. The 656P2705I3T belongs to this category of oscillators, and it provides a high performance, compact, reliable, and easy to use solution for all kinds of applications.The 656P2705I3T oscillator features a frequency range of 5MHz to 70MHz with a crystal-based frequency control circuit. It offers a high stability of 0.005ppm/°C and up to 0.2 ppm/year aging rate. It is available in two packages including DIP and SMD. Furthermore, it is easy to use and requires minimal external components for operation.

The 656P2705I3T oscillator works in several major steps. First, it acquires the reference clock signal from a crystal oscillator which is then split in two paths. One path goes to the prescaler stage while the other is directly used to drive the output dividers. In the prescaler stage, the clock signal is divided by a factor in order to provide the correct frequency to the main divider N-counter. Then, the output of main divider is connected to the control stage, followed by a phase frequency detector (PFD), charge pump and loop filter. After comparing the two clock signals, the PFD produces a signal which is then used by the charge pump to adjust the loop\'s frequency to match the reference clock signal. Finally, the filtered signal passes through a voltage controlled variable resistor to control the output frequency.

The 656P2705I3T oscillator is widely used in a variety of applications due to its superior performance and ease of use. It is often used in communication systems, such as in radio transmitters or cell phone base stations where precise and stable signal frequencies are required. Additionally, it is also used in automotive, consumer electronics, and medical equipment as well as in consumer applications such as smart watches and drones. Furthermore, it can also be used in industrial automation systems, such as those used in FAB facilities and robots.

The 656P2705I3T helps designers solve the requirement of high reliability and stability in their designs. Its crystal-based frequency control circuit and PLL architecture provide a high accuracy without any complicated circuitry. In addition, its compact size and easy to use features make it suitable for a wide range of applications. Finally, it offers a reliable performance and substantial savings in terms of both time and cost.
