ICS91719AGLF Application Field and Working PrincipleICS91719AGLF is a highly integrated frequency synthesis clock generator designed to generate low jitter clocks of varying frequencies in low power applications. It supports a wide range of applications, including telecommunications, storage, automotive, computing, and industrial. It provides a low-cost solution for clock synthesis in high-performance applications.The ICS91719AGLF is a multi-output clock generator that uses a multi-phase Phase Locked Loop (PLL) architecture to synthesize the output frequencies. It features an integrated low jitter PLL which generates a high frequency reference clock and divides it down to create the desired output clock frequency. The PLL is a digital feedback system that uses a phase detector to compare the phases between a reference clock and the output. The phase error is then corrected to ensure that the output clock remains in lock with the reference clock. The output clock frequency is controlled by changing the frequency of the reference clock, the VCO extent and the dividers within the loop.The ICS91719AGLF includes several integrated control and clocking components. It includes a crystal oscillator and programmable divide for the VCO input frequency, a programmable doubler and an integrated phase detector. The output clock frequencies are also programmable, allowing precision selection of the output frequency.The device employs advanced power scaling techniques to reduce power consumption while providing an output with low jitter. It features a programmable spread spectrum mode to spread out jitter and reduce EMI in the transmitted signal, making it suitable for applications which need high signal integrity. Additionally, the ICS91719AGLF features programmable duty cycle control to optimize the duty cycle of the output signal and minimize signal distortion.In summary, the ICS91719AGLF is ideal for low complexity, low power applications. It offers high performance, low jitter frequency synthesis for clock and timekeeping applications, and can be programmed for both spread spectrum mode and duty cycle control. It is an ideal solution for a range of digital applications and is suitable for a variety of markets including telecommunications, storage, automotive, computing, and industrial.
