Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'X1910' against official Texas Instruments documentation to confirm the exact center frequency or band configuration, as this variant may differ from standard LMX2531 models. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to soldering. Confirm availability through authorized distributors, as lead times may vary based on production cycles.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a wide tuning range up to 3.132 GHz is required alongside integrated VCO functionality. Consider the 36-WQFN package constraints for thermal management and PCB layout. Verify that the 2.8 V to 3.2 V supply voltage aligns with the system power design. Compare performance metrics such as phase noise and spurious emissions against application requirements before finalizing the design.
