Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'LQX' against official Texas Instruments documentation, as standard listings typically use 'LQ'. Confirm AEC-Q100 qualification status if automotive application is required. Check moisture sensitivity level handling requirements during assembly. Ensure the NOPB designation confirms lead-free compliance. Validate the exact part number string with the manufacturer before ordering to avoid substitution errors.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a wide output frequency range up to 3.132 GHz is required with integrated VCO capabilities. Consider the 36-WQFN package constraints for PCB layout. Verify input clock frequency limits, as some sources indicate a maximum of 80 MHz for OSCin. Compare power consumption of 32 mA against system budget requirements. Ensure thermal management strategies align with the exposed pad design.
