Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

661GILFT is a technology for generating a higher frequency clock with a lower frequency clock as a reference clock. It is part of the clock/timing family of technologies, alongside clock generators, phase-locked loops (PLLs), and frequency synthesizers. This technology is essential in many applications, including system clocks, digital signal processing, and circuit design.The term GILFT stands for “General Interpolator/Limiter Frequency Translator.” This technology was first developed by Dr. Shamenjung in his research paper “Recursive Evaluation of Sampled Data.” The basic premise of GILFT is to take a low frequency clock and increase the frequency of it by some amount. This increase in frequency is referred to as the GILFT multiplier.The technology works by taking the low frequency reference clock signal and then using some logic to recreate a high frequency clock with the same phase. This is accomplished by first comparing the shape of the reference clock to a pre-defined “ideal clock signal.” The logic then interpolates the difference between the reference clock and the ideal clock signal and creates an output clock signal with the desired frequency and phase.The GILFT multiplier includes a number of components, such as a shift register, which is used to store clock samples. The shift register is synchronized to the reference clock and is used to generate the interpolation data. The data is then used to reconstruct the high frequency clock signal with a preset phase.The advantage of GILFT is that it is a highly efficient clock synthesizer. The interleaving of the clock information between the low frequency reference clock and the higher frequency output clock allows for a longer frequency range and a higher output frequency range than other types of clock generators. Additionally, GILFT is suitable for low-jitter system clock generation, making it ideal for digital systems.GILFT has been integrated into several products, such as the industry-standard clock generator from IDT. It has also been used in the development of ASICs and other components. In addition, GILFT can be used in radio communication, such as for frequency hopping.In conclusion, GILFT is a powerful and efficient technology for generating high-frequency clock signals from low-frequency reference clock signals. It is a key ingredient of the clock/timing family of technologies and has been used in many commercial products. Its ability to generate a wide range of frequencies and its low-jitter performance make it an ideal choice for many applications.
