ICS953401CFT

Clock/Timing - Application Specific

The ICS953401CFT is a programmable clock generator designed to enable system clock designs that require flexibility, precise timing control, very low jitter and low system power. It integrates a programmable PLL and programmable frequency division and is widely used in telecom, data center and storage solutions. This article will analyze its application fields and working principle.

Application Field

The ICS953401CFT is widely used in telecom, data center and storage systems since it is capable of providing precise timing control, low jitter and low system power. It is suitable for a variety of mission-critical applications including transmission systems, baseband or transceiver systems and storage applications.

The IC also gives clock and fan controllers, thermal and power management ICs, as well as board-level components the flexibility to use syntonization clocks, clock distribution and fan division. Its robust functionality is suitable for frequency ranges from 20kHz to 1GHz.

Working Principle

At the core of the ICS953401CFT is a programmable frequencydivision unit, called the Frequency Divider and Counter. This unit is used to, as its name implies, divide the input frequency from a reference clock down to the desired output frequency. This unit has the ability to divide the frequency, then count down until the desired output frequency is achieved.

The ICS953401CFT also incorporates a programmable phase-lock loop (PLL) which is used to accurately syntonize the frequency division provided by the Frequency Divider and Counter, and to ensure the accuracy of the output frequency over time. The PLL works to program and maintain the accuracy of the clock generation by controlling the frequency, time delay and jitter of the output clock.

Once the IC has been programmed, it can generate the output clock in a wide frequency range, tight jitter and narrow pulse width. The output signal can also be adjusted, providing the system designer with comprehensive fine tuning of the signal and enabling the generation of low jitter, tight timing control and long signal rise and fall times.

Conclusion

The ICS953401CFT Programmable Clock Generator offers designers the ability to configure a wide frequency range with low jitter, accurate timing control and low system power. It integrates a Frequency Divider and Counter and a PLL which provide the power and accuracy required for telecom, data center and storage solutions.
