Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B05767 suffix against the official Skyworks ordering guide. Confirm that the GMR suffix matches the required tape and reel packaging format for the production line. Ensure compatibility with the intended serial interface protocol before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a two-output solution with high jitter attenuation is required. The Si5342D variant specifically limits output frequencies to 350 MHz, distinguishing it from higher-frequency options. Verify that the four-input architecture meets the system's redundancy or multi-source requirements.
