Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'GMR' indicates tape and reel packaging rather than tray packaging when sourcing this component. Confirm that the factory preprogrammed configuration associated with the numerical sequence matches the required frequency plan before procurement. Ensure compatibility with the serial interface requirements during integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SI5344D variant specifically when the application requires an output frequency range up to 350 MHz. This model supports both integer and fractional synthesis modes within its specified range. Verify that the 4-input, 4-output configuration aligns with the system's clock tree requirements compared to other family members like the Si5344A or Si5344B.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D series, which combines fourth-generation DSPLL and MultiSynth technologies. The Si5344 sub-family provides four inputs and four outputs in a compact 44-QFN package. These devices are designed for applications requiring high-level jitter performance and flexible clock generation capabilities.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The Si5344A-Dxxxxx-GMR serves as a functional replacement if the application requires output frequencies up to 1028 MHz instead of the 350 MHz limit of the Si5344D. Ensure the new part number includes the correct factory preprogrammed configuration sequence.
