Recent developments in pulse width modulation (PWM), multi-modulation, and wide range frequency synthesizers in the digital field have led to the need for higher levels of performance and accuracy for the development of concepts for the next generation of clock and timing systems. To address this need, MK5811ASLFTR was developed as a highly precise frequency synthesizer with advantages including but not limited to low phase noise, wide output frequency range, adjustable modulation frequency, short settling time and small size.

The MK5811ASLFTR is well-suited for use in application areas such as digital radio systems, communications synchronization, telecommunications systems and even biomedical devices. Its application field covers frequency ranges from 50Hz to more than 8GHz. Its functions provide broad control of frequency, jitter, frequency response, phase noise, and noise pressure.

The working principle of the MK5811ASLFTR is based on a phase-Lock-Loop circuit that allows it to synthesizea precise output frequency depending on a variable input frequency. The output frequency is controlled by the input frequency with a small amount of jitter and phase noise, acting as a stable reference clock in different applications. It includes a voltage-controlled oscillator (VCO) as well as a divide-by-N counter and a phase/frequency detector (PFD). Depending on the reference clock, the divide-by-N counter divider the input frequency to a fraction of the reference clock, which produces the resulting frequency. The PFD constantly monitors the phase difference between the reference clock and the divided input frequency, and then regulates the VCO to reduce the phase difference. As a result, the MK5811ASLFTR is able to hold a steady oscillation frequency relativ to the reference clock.

The core advantage of this specific frequency synthesizer lies in its ability to synthesize wide frequency ranges with precision. By utilizing the divide-by-N counter, the MK5811ASLFTR is able to assume any input frequency in its range and adjust the output frequency by a factor of N. This makes it an ideal tool for applications that require a wide output range with a low phase noise. Other advantages of the MK5811ASLFTR include programmable control of modulation, short settling times and small unit size.

In summary, the MK5811ASLFTR provides a dependable clock source for a wide range of applications at the cutting edge of digital systems. Its application field covers frequency ranges from 50Hz to more than 8GHz. Its precision frequency synthesis technology, stability and accuracy make it an invaluable resource for clock and timing systems. Its small size, adjustable frequency modulation and short settling time make it an ideal tool for applications that require a microcontroller with precision.
