Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix GMR indicates tape-and-reel packaging versus tray options when sourcing. Confirm the factory programming code B05303 matches the required frequency plan, as this part is pre-programmed. Check RoHS compliance status and moisture sensitivity levels before assembly. Ensure the supplier provides valid traceability documentation for the Skyworks manufacturer.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring four distinct clock outputs with ultra-low jitter specifications. Compare against the SI5340A-D-GM variant if generic programmability is preferred over fixed frequencies. Consider the QFN-44 footprint constraints and thermal dissipation requirements for the operating temperature range. Verify compatibility with available development kits like the Si5340-D-EVB for configuration validation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5340 family of MultiSynth clock generators. It shares architectural similarities with other models in the series but differs in output count and package type. The B05303 designation identifies a specific factory-programmed frequency configuration, distinguishing it from user-programmable variants.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The SI5340A-D-GM serves as a functional alternative if reprogrammability is required instead of fixed frequencies. For identical electrical characteristics but different packaging, verify availability of the tray version. Cross-reference with SI5340A-B05303-GM to ensure package consistency.
