Clock Generators, PLLs, Frequency Synthesizers have become ubiquitous in modern electronics. This is largely due to the fact that they fulfill an ever-increasing range of applications and underlying functions; from low-frequency audio output from digital audio systems to high-speed digital signal processing. Among them is the 671M-01LFT, a frequency synthesizer IC that can solve many challenging applications. In this article, we\'ll discuss the 671M-01LFT\'s applications and working principle.

Applications

The 671M-01LFT frequency synthesizer incorporates state-of-the-art technology and covers a wide range of applications. It is designed to provide an accurate, low-jitter clock to frequency up-conversion, frequency multiplication, arbitrary synthesis, and arbitrary clock generation. It is suitable for communication systems, base station applications, radar systems, military applications, as well as industrial automation systems. Furthermore, it is designed to allow operation under extreme environmental conditions. It is also available in a range of packages to suit any size constraints or requirements.

Working Principle

The 671M-01LFT utilizes a fractional-N phase-locked loop (PLL) to convert an input frequency to any desired output frequency. The PLL operates by maintaining the phase difference between the input and output frequencies to be an integer multiple of 2π. The output frequency is determined by the width of the time slot effectively divided by the number of cycles of the reference frequency, which is divided by the internally programmed frequency division ratio. The frequency division ratio is set with an external feed-through capacitor. The capacitor allows the incoming reference frequency to be divided by a ratio of powers of two, with the result being a precise, low-jitter output.

The 671M-01LFT also has a wide operating temperature range and low power consumption, making it suitable for a variety of applications. Furthermore, the device is highly configurable and can be used to synthesize almost any desired frequency. It is also equipped with a patented synchronization algorithm that enables it to transition between two different frequencies/modes without unwanted oscillations and jitter. This ensures excellent clock switching performance.

Conclusion

The 671M-01LFT is a powerful frequency synthesizer IC. It is suitable for a wide range of applications, from communication systems to industrial automation, and its low-jitter output and configurability make it highly desirable for those looking for an accurate, low-power clock source. Its ability to switch between modes or frequencies quickly and accurately with its patented synchronization algorithm makes it even more desirable. As such, the 671M-01LFT is an ideal choice for a variety of clock and timing applications.
