Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'X2570' against official Texas Instruments documentation to confirm exact factory tuning parameters. Ensure compatibility with standard WQFN-36 reflow profiles due to moisture sensitivity classification. 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 output frequency range up to 3.132 GHz is required with low power consumption. The integrated VCO simplifies board layout compared to discrete solutions. Ensure the design supports the 2.8 V to 3.2 V supply rail and accommodates the thermal requirements of the 36-WQFN package.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2531 family of high-performance frequency synthesizers. Other variants in the series, such as LMX2531LQ2820E/NOPB and LMX2531LQ1146E/NOPB, share similar architectural features but differ in factory-set frequency tuning ranges. The family is designed for demanding RF applications requiring stable and clean signal generation.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other LMX2531 variants like LMX2531LQ1570E-NOPB or LMX2531LQ3010E-NOPB if the specific frequency offset matches. Verify pinout compatibility and ensure the replacement part meets the same AEC-Q100 qualification and WQFN-36 package constraints.
