Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory configuration code associated with the B04543 suffix against official Skyworks documentation to ensure correct frequency and protocol settings. Confirm availability status as this variant may be subject to limited distribution or end-of-life transitions compared to standard D-series packages. Request current lifecycle notices prior to finalizing procurement plans.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when ten distinct clock outputs are required with strict phase noise constraints. Ensure the design accommodates the QFN-64 thermal requirements and I2C/SPI programming interface. Compare against SI5341B-D variants if generic programmability without fixed factory configuration is preferred for prototyping flexibility.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341 MultiSynth family, designed for precision timing in complex digital systems. It integrates a low-noise PLL and multiple VCXOs to achieve superior jitter attenuation. The B-suffix indicates a factory-programmed version, distinguishing it from user-programmable counterparts by offering a fixed, optimized configuration out of the box.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

SI5341B-D-GM serves as a comparable alternative within the same series, offering similar electrical characteristics but with user-programmable flexibility rather than fixed factory settings.
