Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer designation carefully, as listings may attribute this part to Rochester Electronics or National Semiconductor/TI. Confirm the specific suffix '2265E' matches the required tape-and-reel or bulk packaging configuration. Ensure the component meets the specified commercial temperature grade (-40°C to 85°C) for your application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a low-voltage (3V), compact PLL synthesizer is needed for frequencies up to 80 MHz. The LLP-36 package is suitable for space-constrained designs. Verify that the BICMOS technology and commercial temperature rating align with the system's power and thermal requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2531 family of frequency synthesizers. Variants such as LMX2531LQ1650E share similar electrical characteristics and packaging but differ in ordering suffixes which may indicate specific manufacturing lots, packaging types, or minor revision differences. The core functionality remains consistent across the series.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other LMX2531 variants like LMX2531LQ1650E, provided the suffix difference does not alter functional parameters. Cross-reference with Texas Instruments documentation to confirm pin compatibility and electrical equivalence before substitution.
