Texas Instruments LMK04033BISQ
LMK04033BISQ variants from Texas Instruments
LMK04033BISQ 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: 48-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.
- 3 distinct suffix patternsExamples: E/NOPB, NOPB, X/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
Ordering Variants
Compare 3 LMK04033BISQ part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |

How to Choose the Right LMK04033BISQ Clock Generators, PLLs and Frequency Synthesizers
Match the footprint first
Packages here: 48-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 LMK04033BISQ, 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 "LMK04033BISQ" — include the full suffix (e.g. E/NOPB, NOPB, X/NOPB). RFQ with reel/tube preference and required date code.
