Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify availability status directly with Skyworks Solutions Inc. or authorized distributors as this specific suffix may be subject to limited stock or special order constraints. Confirm RoHS compliance and moisture sensitivity level prior to PCB assembly planning. Ensure ESD protection protocols are followed during handling due to the fine-pitch QFN-64 package requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when ten synchronized outputs are required with sub-picosecond jitter specifications. Compare against other Si5341 variants if different output counts or frequency ranges are needed. Validate that the 350 MHz maximum output frequency meets system clocking needs. Check compatibility with existing I2C/SPI configuration interfaces used in the design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341 family of MultiSynth clock generators designed for low-jitter applications. It shares core architectural features with siblings like SI5341B-D-GM but differs in factory-programmed frequency coefficients defined by the B05605 suffix. The device integrates a phase-locked loop and differential VCXO for stable frequency generation without external resonators.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other SI5341B variants with identical pinouts such as SI5341B-D-GM, though frequency configurations will differ. Verify electrical parameters match exactly before substitution. Generic clock generators lack the integrated jitter attenuation capabilities.
