The CY25100ZXIF is a highly configurable clock generator chip created by Cypress. It features an ultra-low jitter output and the ability to produce a wide range of frequencies periodically or continuously with any given voltage. The chip is ideal for any application which requires precise timing, accuracy, and stability.

The chip is typically used in devices requiring deterministic frequency synchronization such as data converters, microprocessors, high-speed memories, and communications systems. It boasts a wide operating temperature range making it well suited for a variety of applications from high-end automotive tasks to low-power consumer and industrial products.

Cypress’ CY25100ZXIF works by taking an input signal, either a crystal oscillator or a high-speed clock, and transforming it into a range of frequencies which can be used in the target application. The chip is capable of generating up to four frequency outputs from a single reference signal. Output frequencies can be manipulated directly from the I2C or SPI bus without the need for extra programming.

The operating principle behind the CY25100ZXIF is based on two separate modules. The first module is a built-in PLL frequency synthesizer which takes an input frequency as a reference signal and then intelligently reconstructs multiple frequencies based on the predefined division ratio. The second module is a digital low jitter divider which takes the reconstructed PLL reference signal and divides it into even lower frequencies. It also supports external clock inputs of up to 250 MHz.

The CY25100ZXIF is capable of providing a wide range of frequencies from a range of outputs from kilohertz (kHz) to beyond 100 megahertz (MHz), and boasts a low output jitter of less than 1 picosecond (ps) as well as a low power rating of under 300 microwatts (μW). These factors make it an attractive choice for timing-sensitive applications in which accuracy, low power consumption, and minimal jitter are all of the utmost importance.

The CY25100ZXIF is an incredibly versatile clock generator chip. As a result, many different industries have adopted it for use in various applications. The chip is especially well-suited for use in the Broadcast, Imaging & Video, Intelligent Communications, Automotive Sensors & Safety, and Industrial Automation industries, as well as many others.

Cypress’ CY25100ZXIF is a reliable and cost-effective clock generator chip ideal for a variety of applications. Its two integrated modules, PLL frequency synthesizer and digital low jitter divider, offer highly flexible performance capabilities. The chip’s support for input frequencies of up to 250 MHz and its range of output frequencies from kHz to beyond 100 MHz, combined with its low jitter and low power rating make it an excellent choice for timing-sensitive applications that demand precision and accuracy.
