Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix GMR indicates tape-and-reel packaging when sourcing this component. Confirm that the B05674 code corresponds to the required frequency plan, as custom part numbers are generated via ClockBuilderPro software. Ensure compatibility with the QFN-44 footprint and check for moisture sensitivity handling requirements during assembly. Cross-reference the manufacturer datasheet for the latest revision status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for applications requiring four independent clock outputs with high flexibility. The device replaces discrete oscillators and buffers, simplifying board design. Verify that the required output voltage levels match the supported formats like LVDS or LVPECL. Consider the thermal characteristics of the QFN-44 package for heat dissipation. Use ClockBuilderPro to define the exact frequency ratios before ordering the specific B-code variant.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5340 series of any-frequency, any-output clock generators. It shares architectural similarities with the Si5341 but offers four outputs instead of ten. The series utilizes proprietary MultiSynth fractional synthesizer technology to achieve zero ppm error. It is designed for systems requiring high precision and low phase noise across a wide frequency range.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other variants within the Si5340 family, such as SI5340A-D-GM, provided the output count and frequency specifications align. Check if alternative packages like GM (tray) are available if reel packaging is not required. Ensure that any substitute maintains the same jitter performance and output format capabilities.
