Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B04699 against official Skyworks documentation to confirm the exact frequency plan and pin configuration. Ensure compatibility with the target board's power supply rails and I2C bus requirements. Confirm moisture sensitivity level handling procedures during assembly. Check for end-of-life status or recommended new designations if sourcing for long-term production.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multi-output flexibility and low jitter are critical. Compare the SI5341A series against other Skyworks synthesizers based on required output count and maximum frequency. Validate that the 750 MHz maximum input frequency meets the reference clock source capabilities. Consider thermal dissipation requirements given the 120 mA typical current draw in the QFN-64 package.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 family of Any-Frequency Clock Generators. These devices integrate multiple VCXOs and PLLs to generate stable clocks from a single reference. The A variant typically supports higher output frequencies compared to B or C variants. The GMR suffix indicates tape and reel packaging for automated surface-mount assembly.
