Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'RHAT' against the manufacturer's official documentation to confirm the reel packaging quantity and tape-and-reel specifications. Ensure that the ordering information matches the exact part number required for the intended production volume. Cross-reference the datasheet revision history to confirm compatibility with current design requirements before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a wide tuning range extending to 6.4 GHz is required alongside low power consumption constraints. Compare it against the LMX2572LPRHAT if a lower output frequency limit of 2 GHz is sufficient for the application. Consider the LMX2582 or LMX2592 models if higher performance metrics or extended frequency ranges beyond 6.4 GHz are necessary for the system design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2572 family of wideband RF synthesizers from Texas Instruments. It shares the same VQFN-40 package form factor with other variants such as the LMX2572RHAR and LMX2572EVM evaluation module. The family is designed to address the needs of modern wireless communication standards requiring flexible frequency synthesis capabilities.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

LMX2572RHAR serves as a direct alternative with identical electrical characteristics but may differ in packaging configuration. For lower frequency requirements, the LMX2572LPRHAT offers a 2 GHz limit with similar pinout compatibility. Higher performance needs may require upgrading to the LMX2582 or LMX2592 series.
