Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin carefully, as Ramtron was acquired by Cypress and subsequently Infineon. Ensure the component matches the specific 24-pin QFN EP package designation. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the part number with official Cypress/Infineon documentation to avoid counterfeit or obsolete stock issues.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single IC must generate four distinct clock signals within the 3MHz to 166MHz range. It is suitable for applications requiring low jitter and precise synchronization across multiple system buses. Consider the thermal performance of the QFN EP package for heat dissipation requirements in dense PCB layouts.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the family of programmable clock generators produced by Ramtron, which became part of Cypress Semiconductor following an acquisition. These devices are categorized under analog and mixed-signal integrated circuits, specifically serving as clock buffers and drivers for complex electronic systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Consult official Cypress or Infineon databases for direct pin-compatible substitutes. Verify that any alternative maintains the quad-output structure and the 3MHz-166MHz operational frequency range. Ensure package compatibility with the existing 24-pin QFN footprint.
