ICS932S203AFLNT are integrated programmable clock synthesisers, specially designed for use in personal computer and distributed system applications. They are designed to provide a wide range of comprehensive, low skew, high precision output clocks to support a variety of digital devices, including those typically found in system timing needs.

The ICS932S203AFLNT is suitable for applications requiring small size and low power, such as digital audio and video, imaging, computer and communications systems. Featuring a low power consumption and optimized power features, the part is suitable for use in commercial and industrial settings that require very low quiescent current and very low jitter, for clocks. The ICS932S203AFLNT supports both type 3 and type 5 operation at a variety of frequencies.

ICS932S203AFLNT has many advantages in the application field. Firstly, its multitone output provides tremendous flexibility in system clocking. Since it can synthesize up to 4 output clocks from a single reference frequency, it reduces the need for additional clocks and components in the system. Thus, reducing the number of components and overall cost associated with the system. Another advantage of the ICS932S203AFLNT is its phase locked loop (PLL) technology, which provides extremely low jitter and high precision output clocks. With a total phase jitter of less than 0.5ps, the ICS932S203AFLNT is suitable for applications that require very high frequency accuracy and repeatability.

In terms of its working principle, ICS932S203AFLNT uses a well-known frequency synthesis method termed fractional-N synthesis. It takes a reference oscillator signal and divides it by a programmable integer (I) to a synthesized frequency that is used to generate an output clock that has a programmable frequency range from 1Hz to over 1GHz. The fractional divider used in this case is a delta-sigma fractional divider that allows for fractions of the output frequency. This allows for programs of different frequencies to be constructed from a single reference frequency.

Moreover, the ICS932S203AFLNT also supports on-chip trimming solutions which enable higher accuracy in applications such as mobile communication, clock buffering, and clock amplification. Through its on-chip trimming capabilities, the ICS932S203AFLNT can be made to have a frequency error of less than 50 ppm, thus providing even more accuracy in its output.

In addition to its fractional-N synthesis and on-chip trimming capabilities, the ICS932S203AFLNT also contains an array of digital support circuitry; such as, on-chip voltage-controlled oscillators (VCO), phase locked loops (PLLs), multiplexers and a clock switching circuit. This enables the user to program different clock outputs with different frequency, duty cycle and phase configurations.

To conclude, the ICS932S203AFLNT is a programmable clock synthesizer that allows for low power, high precision output clocks. It features fractional-N synthesis and on-chip trimming capabilities, as well as a wide array of digital support circuitry. By reducing the number of components and overall cost associated with a system, the ICS932S203AFLNT is perfectly suitable for use in a variety of commercial and industrial settings.
