Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'KZXIF' against official Infineon/Cypress documentation to confirm pinout, lead finish, and tape-and-reel specifications. Ensure compliance with RoHS directives as required by your assembly process, noting that earlier revisions of this family may have different environmental statuses. Confirm availability through authorized distributors.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a low-cost, single-output spread spectrum solution is needed for frequencies up to 200MHz. Compare against the CY25100SXC series if field-programmability is required instead of factory-fixed settings. Ensure the 8-SOIC package fits the PCB footprint constraints and that the 3.3V nominal supply aligns with the system power rails.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY25100 family of spread spectrum clock generators from Cypress Semiconductor, now part of Infineon Technologies. These devices are designed to replace fixed-frequency oscillators in applications where reducing EMI emissions is critical without compromising signal integrity.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY25100 variants such as CY25100ZIF or CY25100SXC-xxxAT, provided the output frequency and modulation parameters match the design requirements. Verify package compatibility and electrical characteristics before substitution.
