Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'NOPB' against official datasheets to confirm lead-free status and RoHS compliance. Confirm the exact output frequency band associated with the '1650' variant, as this number typically denotes a specific factory-set center frequency or tuning range within the broader LMX2531 family specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency synthesizer solution is required within the 553 MHz to 3.132 GHz range. Ensure the application supports the 36-pin WQFN footprint and can accommodate the 32 mA current draw. Verify that the target environment meets the -40°C to +85°C operating temperature requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2531 series of PLL frequency synthesizers. The 'LQ' designation indicates the WQFN package type, while '1650' specifies the unique internal configuration or frequency setting. The 'E' often denotes an engineering sample or specific revision, requiring careful verification against mass production data sheets.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other LMX2531 variants such as LMX2531LQ1146E/NOPB or LMX2531LQ2820E/NOPB, provided the specific frequency requirements match. Cross-referencing the exact output frequency and pin compatibility is essential before substitution.
