Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or certified suppliers. Confirm that the specific suffix matches the required package and tape-and-reel specifications. Request original manufacturer documentation to validate lot codes and ensure compliance with RoHS directives before integration into production lines.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when ten distinct clock domains are required with sub-picosecond jitter constraints. Ensure the design accommodates the QFN-64 thermal requirements and validates compatibility with the supported output voltage levels. Compare against the SI5341B-D variant if higher maximum frequencies exceeding 350 MHz are necessary for the target application architecture.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341 series of Ultra-Low Jitter Clock Generators. It shares core architectural similarities with other members like the SI5341B-D11258-GM but differs in factory-programmed output configurations. The series utilizes MultiSynth technology to provide flexible clock synthesis solutions for complex system-on-chip environments.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional substitutes include other SI5341B variants such as SI5341B-D11258-GM or SI5341B-D07274-GM, provided their pre-programmed frequency plans match the design requirements. Verify pinout compatibility and thermal characteristics when swapping between different suffixes within the same package type.
