Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct configuration. Confirm that the integrated reference variant matches the design requirements, as external references are not compatible with this grade. Check for RoHS compliance status and humidity sensitivity handling procedures during storage and assembly.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when board space savings from an integrated reference are prioritized over external crystal flexibility. Ensure the application requires 12 output clocks and supports the specified voltage and temperature ranges. Verify compatibility with ClockBuilder Pro software for configuration. Consider the fixed loop bandwidth characteristics inherent to this grade compared to other variants.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5395 family, which combines fourth-generation DSPLL and Multi-Synth technologies. The J-grade specifically denotes the inclusion of an integrated reference oscillator, distinguishing it from A/B/C/D/P grades that require external crystals. It serves as a high-performance solution for applications demanding low jitter and high integration levels.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The Si5395A-A-GM is a drop-in compatible alternative but requires an external crystal reference instead of the integrated one. Other Si5395 variants with different output counts or frequency ranges may not be functionally equivalent. Verify pinout and package dimensions remain identical before substitution.
