Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'A' against official documentation, as standard listings often reference the 'UTM' variant. Confirm RoHS compliance status, as some LMX2331 variants are explicitly marked non-compliant. Check current availability status, as this series may be discontinued or subject to long lead times depending on the manufacturer's production schedule.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-channel synthesizer with high-frequency output up to 2GHz is required. Ensure the design accommodates the 20-TSSOP footprint and 2.7V to 5.5V power supply constraints. Verify that the application does not require differential outputs, as this model provides single-ended CMOS outputs only.
