Texas Instruments LMX2541SQ
LMX2541SQ variants from Texas Instruments
LMX2541SQ Overview
What changes between part numbers, and what to check before you lock the BOM — Clock Generators, PLLs and Frequency Synthesizers.
Key Features
- Footprint / package: 36-WFQFN Exposed PadSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 5 distinct suffix patternsExamples: 2380E/NOPB, 2690E/NOPB, 3030E/NOPB, 3320E/NOPB, 3740E/NOPB. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Clock Generators, PLLs and Frequency Synthesizers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

How to Choose the Right LMX2541SQ Clock Generators, PLLs and Frequency Synthesizers
Match the footprint first
Packages here: 36-WFQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LMX2541SQ, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "LMX2541SQ" — include the full suffix (e.g. 2380E/NOPB, 2690E/NOPB, 3030E/NOPB). RFQ with reel/tube preference and required date code.
