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 grade matches system requirements for free-run stability. Check for humidity sensitivity handling procedures during assembly. Ensure compatibility with ClockBuilder Pro software for programming. Validate package dimensions against PCB footprint specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when an integrated reference is preferred over external crystals to save board space. Choose this part for applications requiring two differential or single-ended outputs. Verify that the required output frequency range falls within the 1028 MHz limit. Consider the thermal dissipation characteristics if operating at maximum load. Ensure the serial interface protocol matches the host controller capabilities.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5392 family, which offers two outputs. It is functionally similar to the Si5394 (four outputs) and Si5395 (twelve outputs). The 'J' grade indicates the presence of an integrated reference, distinguishing it from 'A' through 'P' grades that require external references. It serves as a drop-in replacement for older Si534x series devices.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The Si5392K-A-GM is a compatible alternative within the same family offering integer-only synthesis. The Si5392L-A-GM provides integer-only synthesis with a higher frequency range. External reference variants like the Si5392A-A-GM require different peripheral components.
