Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix B04124 against official Skyworks documentation to confirm the exact frequency plan and pinout configuration. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity level requirements during storage and handling. Ensure the GMR reel packaging matches assembly line specifications. Validate that the component is not obsolete or restricted in your region.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four independent low-jitter clocks are required below 350 MHz. Compare against the SI5340A series if higher output frequencies near 1 GHz are needed. Consider the SI5341 series for designs requiring ten outputs instead of four. Evaluate power consumption differences between 1.8 V and 3.3 V operation modes. Verify package compatibility with QFN-44 footprints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5340 family of Ultra-Low Jitter Clock Generators. It utilizes MultiSynth technology to generate multiple clock signals from a single reference. The D suffix typically denotes specific jitter performance characteristics within the product line. It serves as a critical timing solution for replacing discrete oscillator arrays in complex digital systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5340 variants with matching output counts and frequency ranges. Verify that substitute parts support the same output voltage levels and jitter specifications. Cross-reference pinouts to ensure QFN-44 compatibility. Confirm that the replacement maintains the required operating temperature range.
