Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific B06230 suffix against Skyworks documentation to confirm the exact preprogrammed frequency plan and configuration parameters. Factory preprogrammed devices are assigned unique numerical sequences representing their specific settings. Ensure compatibility with the target application's required output frequencies before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when ultra-low jitter performance near 90 fs rms is required alongside flexible frequency synthesis capabilities. The Si5344 variant provides four outputs suitable for complex timing architectures. Utilize ClockBuilder Pro software to validate that the preprogrammed configuration meets all system requirements without needing additional field programming.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D series, which utilizes Skyworks' proprietary MultiSynth technology. The Si5344 specifically offers four inputs and four outputs in a compact 44-QFN footprint. This family is designed for high-performance applications requiring precise jitter attenuation and any-frequency multiplication capabilities.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5344 variants such as Si5344A-D-GM or Si5344B-D-GM. Note that standard variants require external programming, whereas the B06230 suffix indicates a factory preprogrammed unit. Verify that the replacement matches the specific frequency plan if the original configuration cannot be replicated.
