Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers are essential components in the telecommunications industry and have many potential applications, such as signal and time synchronization, signal processing, frequency conversion, and channel selection.The MK5811S is one of the popular clock generator chips in the industry, and it has many advantages, such as low power consumption, small size and excellent performance.In this article, we will analyze the application field and working principle of the MK5811S.

The MK5811S is a wide-band, low-power CMOS digital programming synthesizer module, which integrates a low-noise digital PLL, dual dividers and a I2C-programable memory (EEPROM) for up to 6 programmable settings.It can accurately provide a wide range of output frequencies ranging from 20 KHz to 780 KHz.It has various features for electrical, mechanical and optical performance, as well as a wide output frequency suitable for a variety of system frequency requirements.The pin arrangement is symmetrical and the package is small, making the device easier to solder and mount.The product has a high cost performance.

The application field of MK5811S is very wide.It can be used to synthesis the frequency of commercial broadcasting, telecommunication and embedded signal.It is suitable for frequency synthesis with stable working time and small size.It can also be used in satellite communication and other communication fields.It can provide high-performance frequency synthesis output with low power consumption, which makes it suitable for many mobile systems.It is suitable for antenna frequency synthesis, frequency synthesizers, frequency converters, PLL synthesizers, time converter, channel selection and other occasions requiring frequency synthesis.

The working principle of MK5811S is quite complicated because it involves many components.In general, it has a digital PLL loop with a sawtooth oscillator.The sawtooth oscillator generates a sawtooth wave which is fed back to the digital PLL.The digital PLL will then compare the feedback signal with the reference signal from the external reference clock, and the difference between the two signals will be used to generate a VCO control voltage.The VCO control voltage will vary until it reaches the state at which it is synchronized to the reference signal.When this happens, the frequency of the output signal will be locked to the frequency of the reference signal.

At the same time, there is a divider module in the chip.The dividers receive the output signal of the VCO and divide it down according to the settings of the EEPROM.Then, the divided signal can be output under different scenarios.Finally, the required output frequency can be obtained through the combination of the dividers and the VCO.

In conclusion, the MK5811S clock generator is s a low-power and wide-band CMOS digital programming synthesizer module.It is suitable for frequency synthesis with stable working time and small size.It is suitable for a variety of applications such as signal and time synchronization, signal processing, frequency conversion, and channel selection.The working principle is highly complex, but the bottom line is that the device is capable of accurately providing a wide range of output frequencies ranging from 20KHz to 780KHz.
