LMX2572LPRHAT

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2572LPRHAT is a wideband RF synthesizer manufactured by Texas Instruments, belonging to the LMX2572LP series. It operates within an output frequency range of 12.5 MHz to 2 GHz and accepts input frequencies between 5 MHz and 250 MHz. The device functions on a single 3 V to 3.5 V power supply, drawing approximately 70 mA at a nominal 3.3 V. It is housed in a 40-pin VQFN package designed for surface mount installation. The component supports operation across a temperature range of -40°C to +85°C and utilizes silicon technology.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'RHAT' against official datasheets to confirm tape-and-reel packaging and moisture sensitivity classification. Ensure compatibility with the LMX2572LP family specifications before integration into designs requiring precise power consumption profiles.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a 2 GHz upper frequency limit suffices, distinguishing it from the standard LMX2572 which reaches 6.4 GHz. Consider the VQFN-40 footprint for board space constraints. Verify that the 70 mA current draw aligns with system power budgets compared to higher-performance alternatives.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2572LP family, characterized by low power consumption. It serves as a specialized variant of the broader LMX2572 series, offering a reduced frequency range optimized for specific bandwidth requirements while maintaining the core phase-locked loop performance features of the parent product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

LMX2572RHAR provides a 6.4 GHz output range but shares the same VQFN-40 package and general interface characteristics.
