Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers is a technology used in electrical engineering and computer science, which is machined with-and-controllable frequency. For example, a programmable clock generator composed of a phase-locked loop (PLL) uses clock and timing signals in media and technology devices such as radio frequency, audio and video applications.

The ICS663M is a new family of fractional-N frequency synthesizers, which are designed to offer clock and frequency synthesizing capabilities. Its objective is to provide a simple, low noise and unit cost, frequency synthesizer for applications with cost constraints.

The ICS663M has a wide range of application fields including RF applications, communications, electrical engineering and computers, especially audio and video. It has the capability to provide various frequencies with a wide range of modulation. It also has low power consumption and does not require too much power. Highly versatile ICS663M is programmable to support a wide variety of applications.

The ICS663M has a simple working principle. The PLL includes three major blocks: filter, phase-frequency detector and voltage-controlled oscillator. Firstly, the filter takes the input signal and produces a clean and stable reference frequency. Secondly, the phase-frequency detector detects the frequency differences between the reference frequency and output signals, and it controls the loop gain. At last, the voltage-controlled oscillator uses the feedback loop and implements the PLL.

To sum up, the ICS663M provides an outstanding frequency synthesizer to meet a wide range of application fields. It is capable of accurate control of multiple frequency outputs, working with a very low noise, high precision, and low power consumption. The working principle of the ICS663M is based on the simple yet effective PLL with filter, phase-frequency detector and voltage-controlled oscillator.
