Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'SQ' against official datasheets to confirm the exact grade and packaging configuration. Ensure compatibility with the LMX24856211EVAL development kit if prototyping. Confirm RoHS compliance details and moisture sensitivity levels prior to assembly planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a dual-loop solution is required within the 500 MHz to 3 GHz range. Compare power consumption metrics against the LMX2486 series if higher frequency coverage up to 4.5 GHz is needed. Verify that the WQFN-24 package fits the target PCB footprint constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2485 family of low-power PLLs. It shares architectural similarities with the LMX2486 but targets lower frequency bands. Both devices utilize similar packaging and interface standards, facilitating design flexibility across different RF frequency requirements within the same product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The LMX2486SQ/NOPB serves as a functional substitute for higher frequency needs, covering 1 GHz to 4.5 GHz. Verify pinout compatibility and control register settings before swapping, as performance characteristics differ significantly at upper frequency ranges.
