CY22800KFXCT is a low-power and high-performance clock generator and PLL (phase-locked loop) frequency synthesizer. It is the industry\'s first integrated solution designed to reduce the frequency synthesizer cost and simplify the system design process.CY22800KFXCT is suitable for use in applications such as digital AV (audio and video) systems, digital oscilloscopes and home automations systems. With its robust and flexible features, the device can be applied to a wide range of frequencies and performance requirements.The CY22800KFXCT features a built-in PLL frequency synthesizer, a dual-loop modulator, and a frequency_divider_based_divider circuit. It also supports up to 4 output frequencies, and includes an optional output buffer feature. The device requires very few external components and has minimal power consumption. Its advanced feature set allows for its use in various applications with varying performance requirements.The basic architecture of the CY22800KFXCT consists of two main blocks: a Programmable Divider and a Digital Timing Subsystem. The Programmable Divider is used to divide the reference clock frequency to match a predefined frequency. The Digital Timing Subsystem operates the frequency synthesizer, which is a programmable divider used to generate the desired output signals.The CY22800KFXCT Programmable Divider is used to divide the reference clock frequency to match the desired output frequency. The divider contains both a standard 16-bit divider (for frequencies up to 1.6GHz) and a 32-bit divider (for frequencies up to 4GHz). The Digital Timing Subsystem operates the frequency synthesizer and is responsible for generating the desired output signals. The frequency synthesizer consists of a dual-loop modulator and a frequency divider-based divider.The Dual-Loop modulator is responsible for generating the different output frequencies. It works by initially setting the phase frequency detector (PFD), and the loop filters, which differ depending on the application, to the desired phase and frequency of the output. The phase frequency detector then compares the output of the phase detector with the input and adjusts the phase tracking loop accordingly. The frequency divider-based divider is used to toggle the output frequency by dividing the output of the PFD. The frequency divider consists of a series of high-speed D flip-flops, which can provide either a binary or a quadrature output.The CY22800KFXCT also includes a number of additional features such as the optional output buffers, programmable reference clock frequency, and a power saving mode. The power saving mode allows the device to reduce power consumption when the device is not being used. The integrated output buffers can be used to isolate the output sinusoids, which are essential for certain applications.To sum up, the CY22800KFXCT is a low-power, high-performance clock generator and PLL frequency synthesizer. It provides up to 4 output frequencies and requires little external components for its applications. It can be used for digital AV, digital oscilloscopes and home automation systems. The device also includes other features such as the programmable reference clock frequency and the output buffers. The device is suitable for applications which require varying performance level and frequency range.
