Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'EP' indicates enhanced performance or reliability specifications compared to standard commercial variants. Confirm that the 48-VFQFN package with exposed pad matches the thermal and mechanical requirements of the target PCB design. Ensure compatibility with the required 3.3 V power rail and check moisture sensitivity levels for proper handling during assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a wide tuning range extending beyond 10 GHz is required within a single integrated circuit. Consider the 360 mA supply current for adequate power budgeting and thermal management solutions. Evaluate the -55°C to 115°C temperature range against environmental constraints to ensure long-term reliability in demanding operational scenarios without requiring additional cooling measures.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2694 family of wideband RF synthesizers. It serves as the enhanced performance (EP) variant packaged in a surface-mount VFQFN format.
