Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix B04477 against official Skyworks documentation to confirm the exact frequency plan and pinout configuration. Ensure that the QFN-64 package handling requirements are met during assembly. Confirm RoHS compliance status through the manufacturer's current datasheet before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when ten synchronized outputs are required with frequencies under 350 MHz. Compare the 90 fs jitter specification against system timing budgets. Evaluate the QFN-64 thermal characteristics against PCB layout constraints. Verify input frequency limits do not exceed 750 MHz for proper PLL operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 family of ultra-low-jitter clock generators. It shares core architectural features with variants like SI5341B-D-GM but differs in factory-programmed frequency parameters. The B-series designation indicates a specific custom configuration within the broader Si5341 product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Generic replacements may not match the specific frequency plan encoded in the B04477 suffix. Consider SI5341B-D-GM or SI5341B-D11258-GM if reprogramming capabilities are acceptable. Verify pin-to-pin compatibility and electrical specifications before substitution.
