The CY22395FXC Clock Generator is a highly integrated Silicon-based frequency synthesizer and clock generator system-on-a-chip that supports a wide range of frequencies and applications. The IC is designed to provide a low-cost, low-power, composite frequency generator solution for desktop, laptop, and embedded systems. In addition, the CY22395FXC offers a wide variety of features such as four-line multiplexer/demultiplexer (MUX/DEMUX) outputs, phase-locked loop (PLL) synthesizers, phase-matched and adjustable outputs, programmable clock sources, and programmable logic arrays (PLAs).

The CY22395FXC’s application field focuses on the high-precision clock generator system, providing accurate and low-power clock sources and outputs suitable for computer systems and embedded applications. It supports a wide range of frequencies between 2 MHz and 1.5 GHz. The supported frequencies can be divided into two categories: Peripheral Clock Generator (PCG) and Clock Generator Interface (CGI).

The PCG provides multiplexed outputs with programmable parameters such as multiplexer/demultiplexer (MUX/DEMUX) outputs and phase-matched outputs. The CGI is responsible for generating frequencies up to 1.5 GHz, and it is designed for high-performance system clock solutions that offer low jitter and high frequency resolution. Furthermore, the PLLs of the CY22395FXC offer a wide range of features such as programmable reference frequencies, adjustable bandwidths, and fast switchover from blocked-to-force mode.

The working principle of the CY22395FXC is based on the concept of frequency synthesis. Frequency synthesis is a process in which multiple signals of different frequencies are generated from a single source. This is achieved by combining several basic signal components of different frequencies. Once combined, these components form a single frequency signal. The CY22395FXC is a device that uses this principle to generate frequencies up to 1.5 GHz.

The main components of the CY22395FXC are the on-chip oscillator, the reference frequency generator, and the programmable logic array. The on-chip oscillator generates a master clock signal that is fed to the reference frequency generator. The reference frequency generator is responsible for generating a reference frequency from the master clock signal. This reference frequency is then used as an input to the programmable logic array. The programmable logic array is responsible for creating the various output frequencies based on the reference frequency. The output frequency is determined using the programmable parameters, such as the pre-defined multiplication factor, the frequency select line, and the divider select line. By changing the parameters, the output frequency can be adjusted accordingly.

The CY22395FXC clock generator system is a comprehensive and reliable solution for applications requiring a low-cost, low-power, and low-phase noise clock source. It provides a wide range of frequency outputs, programmable parameters, and programmable logic arrays, making it an ideal choice for embedded and desktop systems. Moreover, its frequency synthesis capability allows for faster and more accurate frequency adjustment, making it an attractive choice for various applications.
