Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm factory preprogramming details. Ensure the component matches the required output frequency range specifications for your design. Confirm package dimensions and thermal characteristics align with your PCB layout constraints before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when an output frequency range up to 350 MHz is sufficient. Verify that the four-input and four-output configuration meets system requirements. Consider the integrated loop filter and NVM capabilities if minimizing external components and ensuring startup stability are priorities. Use ClockBuilder Pro software to configure the specific frequency plan.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5344 Rev D series, which combines fourth-generation DSPLL and MultiSynth technologies. The series includes variants like the Si5344A-D-GM for higher frequency ranges up to 1028 MHz. The Si5344D variant specifically targets applications requiring frequencies up to 350 MHz while maintaining ultra-low jitter performance.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The Si5344A-D-GM serves as a high-frequency alternative within the same package. For lower output count needs, the Si5342 series offers two outputs. Cross-referencing with the Si5345 series provides ten-output options in a larger package.
