Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers is a sub-category of clock products, including MK5814STR. This paper will explain the application field and working principle of MK5814STR.

Application Field of MK5814STR

MK5814STR is a programmable clock synthesizer module which is used in a huge range of applications such as communications, clocks/timing systems, medical equipment and others. It is a type of mission-critical clock, ideal for frequency agile applications, as it can provide signals that can precisely lock onto a wide range of frequencies.

The MK5814STR is an excellent choice for a frequency agile application, since it has an impressive range of output frequency ranging from 1 Hz up to 156 MHz. The frequency range of MK5814STR is wide enough to support multiple applications and can be programmed using the programming interface, allowing both the optimal frequency range and agility in frequency and phase requirements.

Working Principle of MK5814STR

The MK5814STR is a programmable clock synthesizer module that is designed to generate accurate timing frequencies without the need for adjustments. It works by applying an oscillating waveform to a closed loop circuit. This waveform is then compared to an internally generated reference signal. The frequency of the output waveform is then determined by the difference between the input waveform and the reference signal. If any errors occur, the circuit will automatically adjust the frequency of the output waveform until the circuit is balanced again.

The MK5814STR uses a cascade loop consisting of a reference clock, a digitally controlled oscillator (DCO), a phase/frequency detector (PFD), and a programmable divider. The reference clock is used to provide a stable, low-jitter reference wave. This wave is then fed into the DCO, which is used to generate a wave similar to the reference clock wave, but at different frequencies. The waveforms from the DCO and reference clock then feed into the PFD, which compares the two waveforms in order to maintain the correct frequency of the output waveform. The programmable divider is used to divide the wave frequency up to achieve an output waveform that matches the desired frequency range.

In order to achieve high accuracy and low phase noise, the MK5814STR also employs jitter attenuation technology. The system exploits high accuracy phase-locked loop based frequency synthesis which combines high accuracy sine wave generation and high frequency sinusoidal waveforms. This technology helps reduce jitter noise, enabling the device to achieve reliable operation over a wide range of frequencies. The low phase noise also helps ensure accurate timing and communication between different devices.

Conclusion

The MK5814STR is a powerful and reliable programmable clock synthesizer that is suitable for a wide range of applications. Its broad frequency range and high accuracy make it suitable for a variety of tasks. In addition, its low phase noise and jitter attenuation technology ensure reliable operation over a range of frequencies. These features make the MK5814STR an ideal choice for frequency agile application requirements.
