CY2412SXC-3 is a high-performance, low-jitter, programmable clock generator and synthesizer. This device offers a wide range of clock solutions in the Clock/Timing category and utilizes an integrated phase-locked loop (PLL) to provide excellent jitter/spur performance. The CY2412SXC-3 is an ideal solution for digital or analog clock application requirements in various manufacturing or test applications. It is suitable for use in video, digital signal processing (DSP), gigabit Ethernet (GBE), storage, high-speed serial link, network applications, and more.The CY2412SXC-3 clock generator and synthesizer uses a fractional-N frequency synthesizer architecture that can be programmed to generate a wide range of frequencies from 9 kHz to 500 MHz. The output frequencies are accurate to within ±200 ppm with ±450 ps of jitter, making the device suitable for a wide range of applications.The CY2412SXC-3 clock generator also features an output power of up to +3.3 V, making it suitable for powering high-performance components that require a high-current, low-noise power supply. The device also includes an additional output buffer driver stage that helps to minimize the output impedance and provide clean and stable power output.### Working Principle of CY2412SXC-3 The working principle of CY2412SXC-3 is based on a phase-locked loop (PLL) architecture. In this architecture, the PLL circuit consists of a reference oscillator, phase detector, and a programmable frequency synthesizer. The reference oscillator produces a periodic signal, which is then compared to the input signal using a phase detector. The output of the phase detector is used to control the frequency of the programmable frequency synthesizer.The CY2412SXC-3 phase-locked loop (PLL) is designed to operate under three modes: direct control, manual control, and phase control. In the direct control mode, the reference oscillator is disabled and the input clock signal is directly fed to the PLL to generate the output clock. In the manual control mode, the user is allowed to manually adjust the synthesizer frequency while the PLL remains disabled. In the phase control mode, the user is allowed to adjust the phase of the PLL to fine-tune the output clock signal. Once a desired frequency is set in the programmable frequency synthesizer, the output frequencies are accurate to within ±200 ppm with ±450 ps of jitter, thus making the CY2412SXC-3 suitable for a wide range of applications. The device also features an output power of up to +3.3 V for powering high-performance components. In addition, the CY2412SXC-3 provides excellent jitter/spur performance and is suitable for digital or analog clock application requirements in various manufacturing or test applications. Furthermore, it is also available in both a surface mount (SMT) and through-hole (TH) package, making it a versatile clock solution.In summary, CY2412SXC-3 is an ideal clock generator and synthesizer solution for various clock application requirements. It is a programmable device that utilises a fractional-N frequency synthesizer architecture to produce a wide range of frequencies from 9 kHz to 500 MHz. Its output is accurate to within ±200 ppm with ±450 ps of jitter, making it suitable for a wide range of applications. The CY2412SXC-3 is available in both SMT and TH packages, thus providing versatile clock solutions for industrial and consumer applications.
