Clock Generators, PLLs, Frequency Synthesizers

Clock generators, phase-locked loops (PLLs), and frequency synthesizers play a critical role in wiring up the digital world – they serve as the essential building blocks of modern computing and telecommunications technologies. The MK1709S synthesizer is an innovative frequency synthesizer with many useful features and applications. In this article, we will explore the MK1709S application field and its working principle.

Applications and Features

The MK1709S is a programmable, multi-frequency synthesizer designed for radio-frequency (RF) applications. It has a wide range of application fields, including fixed or mobile wireless communications, radio broadcast, microwave point-to-point links, and test and measurement applications.The MK1709S is a multi-mode frequency synthesizer that can be used for both analog and digital operation. It supports full 6-digit, multi-stage frequency division and five-stage frequency division – resulting in an ultra-wide tuning range of up to 50 MHz. The MK1709S also supports crystal-controlled operation and has a maximum output frequency of 1.22 GHz.The MK1709S includes a wide variety of features, such as low output noise, low power consumption, high PLL bandwidth, wide-frequency agility, and linear frequency range. It also offers very precise tuning resolution and fast locking time. In addition, the MK1709S has a built-in self-test function and supports remote control.

Working Principle

The MK1709S works by utilizing a phase-locked loop (PLL). A phase-locked loop works by comparing a frequency at the input with a reference frequency, which is usually generated by a crystal oscillator. When the input frequency is the same as the reference frequency, the phase difference between the two frequencies is zero. The output frequency of the phase-locked loop is then adjusted until the phase difference is maintained at zero.In the MK1709S, the phase-locked loop is used to control the output frequency of the synthesizer. The input of the PLL is a divided-down form of the crystal frequency, and the output is divided down further to generate the desired output frequency. The MK1709S synthesizer includes a programmable divider to generate the desired frequency division.

Conclusion

The MK1709S synthesizer is an innovative frequency synthesizer with a wide range of applications. It has a wide range of features, such as low output noise, low power consumption, wide-frequency agility, and linear frequency range. The MK1709S utilizes a phase-locked loop to control the output frequency of the synthesizer, and it has a built-in self-test function and supports remote control. In short, the MK1709S synthesizer is a versatile and reliable tool for use in many different types of applications.
