Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer designation as Texas Instruments due to the acquisition of National Semiconductor. Confirm the specific suffix '2380' corresponds to the intended factory preset or configuration variant. Ensure the component meets RoHS compliance standards as indicated by the NOPB suffix. Cross-reference the datasheet for the exact electrical characteristics associated with this specific sub-model.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when ultra-low phase noise is critical for the application. The integrated VCO simplifies design by reducing external component count. Verify that the required output frequency falls within the 32 MHz to 4 GHz range. Ensure the system power supply can maintain the 3.15 V to 3.45 V operating window. Check thermal requirements for the WQFN-36 package in the final enclosure.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2541 family of PLLatinum frequency synthesizers. The 'SQ' prefix typically denotes military-grade qualification or specific reliability standards. The 'NOPB' suffix indicates lead-free packaging. While originally branded under National Semiconductor, current documentation and manufacturing are handled by Texas Instruments following their corporate merger.
