Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory pre-programmed configuration associated with the numerical suffix against the required system timing parameters. Confirm that the ordering suffix matches the desired output frequency plan before finalizing procurement, as custom configurations are assigned by ClockBuilder Pro software.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a dual DSPLL architecture with four outputs is sufficient for the design. Ensure the required output frequencies do not exceed 720 MHz for differential or 250 MHz for LVCMOS. Verify compatibility with the 44-QFN 7x7 mm package dimensions and thermal requirements for the target application environment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5346 family, which features dual DSPLL technology. It serves as a compact alternative to the quad-DSPLL Si5347, offering similar jitter attenuation and flexibility within a smaller 44-pin QFN footprint. The 'A' designation indicates support for output frequencies up to 720 MHz.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The Si5346B-Dxxxxx-GM variant is available but restricts maximum output frequencies to 350 MHz. The Si5347 series offers quad DSPLLs and eight outputs in a larger 64-QFN package. Direct substitution requires verifying that the lower frequency limits or additional I/O counts align with the original design specifications.
