Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific configuration code B04279 against official Skyworks documentation to ensure correct frequency plan and pinout compatibility. Confirm availability status as custom-programmed devices may have restricted distribution channels. Validate RoHS compliance and moisture sensitivity levels prior to integration into manufacturing processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when designing systems requiring ten synchronized clock outputs with frequencies under 350 MHz. Ensure the application environment stays within the specified -40°C to +85°C operational temperature range. Verify that the required output voltage levels match the supported CML, HCSL, LVCMOS, LVDS, or LVPECL options available on the device.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341 family of ultra-low jitter clock generators. It shares core architectural similarities with other variants like the SI5341A and SI5341C, differing primarily in maximum output frequency capabilities and specific factory-programmed parameters defined by the suffix code.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements require matching the ten-output configuration and sub-350 MHz frequency limit. Consider SI5341B variants with identical B-suffix codes for exact functional equivalence. Higher-frequency alternatives like SI5341A may offer broader bandwidth but require verification of jitter performance and power consumption differences.
