Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or certified partners. Confirm RoHS compliance status and check for moisture sensitivity handling requirements prior to assembly. Ensure the specific suffix matches design specifications as ordering codes define package and tape/reel configurations. Request original manufacturer documentation to validate part history and traceability before final procurement decisions.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when ten distinct clock outputs are required with frequencies under 350 MHz. Verify that the QFN-64 package fits the PCB layout constraints. Confirm compatibility with available I2C/SPI programming interfaces for configuration. Evaluate power consumption against system thermal limits given the 115 mA to 120 mA operating current range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5341 series of MultiSynth clock generators. It shares architectural similarities with other models like the SI5341B-D11258-GM but differs in specific factory-programmed frequency plans and packaging variants. The B04570 suffix indicates a specific configuration unique to this order code within the broader Si5341 product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include SI5341B-D11258-GM and SI5341B-D12561-GM for similar 10-output functionality. Verify pin-to-pin compatibility and reprogram configuration files if replacing with different suffix variants. Consult Skyworks documentation for electrical parameter equivalence.
