CY2292SXL-677

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SXL-677 is a programmable clock generator from the CY2292SL series, manufactured by Cypress Semiconductor Corp. It integrates three phase-locked loops (PLLs) to generate up to three custom frequencies from external sources. The device features EPROM programmability, allowing for factory or field configuration. Key technical attributes include low-skew, low-jitter outputs with high accuracy, and configurable operation at either 3.3V or 5V. It supports power management options such as shutdown, output enable, and suspend modes, along with frequency select capabilities.
