Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix RTWT against official datasheets to confirm the reel packaging configuration. Ensure the part number matches the Q1 automotive grade designation if required for your application. Cross-reference the manufacturer's latest documentation to validate pinout compatibility and thermal specifications before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a wide 14 GHz tuning range and integrated modulation features are necessary. It is suitable for designs requiring AEC-Q100 compliance and extended industrial temperature ranges. Compare against the LMX2491 if a lower 6.4 GHz maximum frequency is sufficient for the system requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the LMX2492 family of low-noise fractional-N PLLs. It shares architectural similarities with the LMX2491 but offers an extended upper frequency limit of 14 GHz compared to the 6.4 GHz limit of its counterpart. The family is designed for high-performance RF applications demanding low phase noise and flexible modulation profiles.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

LMX2491RTWR is a related model with a reduced 6.4 GHz maximum output frequency. Verify that the 14 GHz capability of the LMX2492 is not required before substituting.
