Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B04264 against official Skyworks documentation to confirm the programmed configuration, as this identifier denotes a factory-programmed variant rather than a generic functional type. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity levels and recommended reflow profiles prior to assembly. Ensure compatibility with existing system power rails and signal integrity requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring precise clock distribution with minimal phase noise. Compare the 1.028 GHz maximum output limit against application needs. Evaluate the 90 fs jitter specification relative to receiver sensitivity. Consider the QFN-64 footprint for PCB layout constraints. Verify that the required output voltage levels match the available CML, LVDS, or LVPECL options.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This model belongs to the Si5341 family of MultiSynth clock generators. These devices are designed for high-performance applications demanding superior timing accuracy. The series utilizes advanced PLL technology to clean and distribute clocks across complex digital systems. The SI5341A variant specifically targets higher frequency ranges compared to lower-tier models in the lineup.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must maintain the 10-output architecture and 1.028 GHz frequency capability. Devices like the SI5341B-D-GM offer similar functionality but are limited to 350 MHz outputs. Ensure substitute parts support the same output logic families and meet the 90 fs jitter requirement. Verify pinout compatibility with the QFN-64 package.
