MK2772-01S is a fractional-N programmable frequency synthesizer IC. It is part of a family of clock/timing solutions that are well-suited for a variety of applications, including clocks, stepping motors, and active filters. The MK2772-01S uses a digital phase locked loop (PLL) design to generate an accurate frequency from an input clock. It has an adjustable parameter range which can be set to match the desired frequency or desired resolution for the application.

The frequency synthesizer of the MK2772-01S can be programmed for any frequency divider range between 0 & 65535 that corresponds to a step size ranging from 0 to 1 Hz. It has an on-chip voltage-controlled oscillator (VCO) that can be used to generate frequencies up to 76 MHz. The device is packaged in a small QFN package, which makes it suitable for applications where space is a constraint.

The MK2772-01S works on the principle of a phase lock loop. It uses a reference clock (the input clock) as a reference, and locks to it by comparing the phase and frequency of the reference clock with its own internal clock. The PLL is then used to adjust the frequency of the VCO and generate an output clock that is in lock with the reference clock.

The output clock frequency can be fine-tuned using the on-chip programmable frequency divider. This frequency divider is used to divide down the reference clock frequency which can then be multiplied in the PLL to generate the required output frequency. This allows for extremely precise tuning of the output frequency.

The MK2772-01S is ideal for applications requiring low jitter clock generation, such as industrial and automotive control systems, telecommunications systems, and satellite radios. It also has uses in digital audio systems as a clock source for digital-to-analog converters and in test and measurement instruments.

The MK2772-01S is a highly reliable, cost-effective solution for highly accurate clock and timing solutions. It supports a wide range of input frequencies and programmable output frequencies, while providing very low levels of distortion and clock jitter. The features make it an ideal choice for a variety of applications requiring highly accurate clocks.
