Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix code against official Skyworks documentation to confirm the programmed frequency set and pinout compatibility. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Confirm that the target application voltage aligns with the 1.71 V to 3.47 V operating range. Cross-reference the package marking with the QFN-64 physical dimensions to prevent assembly errors.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when ten synchronized outputs are required with frequencies up to 800 MHz. The 90 fs jitter specification makes it suitable for high-bandwidth data links where signal integrity is critical. Compare against the SI5341B series if lower maximum output frequencies suffice, as variants may offer different optimization profiles. Ensure the design accommodates the thermal requirements of the QFN-64 package under continuous operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 family of ultra-low jitter clock generators. It shares the core MultiSynth PLL architecture with other members like the SI5341A-D-GM but differs in its factory-programmed output specifications. The 'B' suffix typically denotes a specific frequency plan or variant within the A-series hardware platform, distinguishing it from generic programmable units.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other SI5341A variants such as SI5341A-D-GM, provided the fixed frequency outputs match the system requirements. Verify that substitute parts maintain the same 90 fs jitter performance and output drive strengths. Check for pin-to-pin compatibility in the QFN-64 footprint to avoid PCB redesign.
