Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'X2265' against official Texas Instruments documentation, as standard listings typically use 'LQ2265'. Confirm moisture sensitivity level (MSL 3) and reflow soldering profile compliance during assembly planning. Ensure ESD protection measures are implemented due to the sensitive RF nature of the integrated VCO and PLL circuitry.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a wide tuning range up to 3.132 GHz is required with minimal external passive components. The integrated VCO simplifies design complexity compared to discrete solutions. Consider the 36-WQFN package thermal performance for high-density PCB layouts. Verify that the 2.8 V to 3.2 V supply range aligns with the target system power architecture.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2531 family of high-performance frequency synthesizers. Variants such as LMX2531LQ1570E/NOPB and LMX2531LQ3010E/NOPB share similar architectural features but differ in factory-set center frequencies or calibration parameters. The family is designed for consistent performance across various RF front-end modules.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other LMX2531 variants like LMX2531LQ2265E/NOPB if the 'X' prefix denotes a specific tape-and-reel or packaging variation rather than a functional change. Cross-reference with LMX2596 or LMX2594 series only if higher frequency ranges or different integration levels are acceptable.
