Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix (B05831) against official Skyworks documentation to confirm the exact frequency plan and pin configuration. Ensure compatibility with the target PCB layout for the QFN-64 package. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference the part number with the manufacturer's current lifecycle status to avoid obsolescence risks.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple low-jitter clock signals are required from a single source. The SI5341A series supports flexible output formats, making it suitable for mixed-signal environments. Compare the 90 fs jitter specification against system timing budgets. Consider the 1.028 GHz maximum output frequency limit relative to downstream receiver requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 family of Any-Frequency Clock Generators. These devices integrate multiple PLLs and synthesizers to generate diverse clock frequencies from a single reference. The family is designed for high-performance applications demanding superior phase noise and jitter performance compared to standard oscillators.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 10-output architecture and 90 fs jitter specification. Verify that alternative parts support the same QFN-64 footprint and voltage ranges. Check if substitute devices offer compatible output drive strengths for CML or LVDS loads.
