CY2544C012

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2544C012 is a quad-phase programmable clock generator manufactured by Cypress Semiconductor Corp. It integrates four independent Phase-Locked Loops (PLLs) to generate multiple output clocks from a single reference input. The device supports spread spectrum frequency modulation to reduce electromagnetic interference (EMI). It features a serial interface for configuration, allowing users to program frequency multiplication factors and spread spectrum parameters. The component is designed for high-performance digital systems requiring precise timing synchronization across multiple domains.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix codes against official datasheets to confirm voltage levels and package types. Confirm RoHS compliance status as older Cypress batches may differ. Check for obsolescence notices since Cypress assets were acquired by Infineon. Ensure the source document matches the exact part number to avoid pinout mismatches.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple clock domains are required from a single reference source. Evaluate the need for spread spectrum functionality to meet EMI regulations. Compare power consumption requirements against other clock generators in the CY25xx family. Verify that the serial interface compatibility matches the host controller's capabilities.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2544 series belongs to Cypress's programmable clock generator lineup, widely used in computing and communications. Following Infineon's acquisition of Cypress, support and documentation are managed under Infineon Technologies. This specific model represents a quad-PLL solution, distinct from single or dual-PLL variants in the same family.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Check for direct substitutes within the CY2544 family with different speed grades or packages. Consider CY2544C013 or CY2544C014 if different output configurations are needed. Verify cross-compatibility with Infineon-branded equivalents after the corporate merger.
