Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'LQE' against official documentation, as standard listings typically reference 'LQ'. Confirm moisture sensitivity level handling procedures due to Yes designation. Ensure the NOPB designation confirms lead-free compliance. Check current availability status as inventory levels fluctuate. Validate that the 36-WQFN package matches the target PCB footprint design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when an integrated VCO solution is required for frequencies up to 3.132 GHz. The AEC-Q100 qualification makes it suitable for automotive environments. Compare power consumption of 32 mA against system budget constraints. Ensure the 2.8 V to 3.2 V supply range aligns with available board rails. Verify thermal performance within the -40°C to +85°C operational window.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2531 series of high-performance frequency synthesizers. The series includes variants like LMX2531LQ1570E and LMX2531LQ3010E, which share similar architectural features but differ in specific tuning or calibration parameters.
