Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the suffix RHAR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the specific revision level against the latest TI documentation to guarantee functional compatibility.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model over the standard LMX2572 when the application requires a maximum output frequency of 2 GHz rather than 6.4 GHz. The LP variant offers reduced power consumption suitable for portable devices. Verify that the required output bandwidth and phase noise specifications align with the device's performance curves in the technical data sheet.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the LMX2572LP series, which focuses on low-power wideband synthesis. It serves as a specialized variant of the broader LMX2572 family, differentiated primarily by its lower maximum operating frequency and optimized power profile for specific wireless infrastructure needs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The LMX2572LPRHAT is the tray-packaged equivalent of this reel-delivered part. For higher frequency requirements up to 6.4 GHz, the standard LMX2572RHAR may be considered if power constraints allow.
