LMX2582RHAR Description

Short technical summary and product information.

The LMX2582RHAR from Texas Instruments is a wideband RF PLLatinum RF synthesizer featuring an integrated VCO. It supports a broad output frequency range from 20 MHz to 5.5 GHz, making it suitable for various RF applications.

 

This device offers industry-leading phase noise performance, with a normalized PLL noise floor of -231 dBc/Hz and VCO phase noise of -144.5 dBc/Hz at a 1-MHz offset for a 1.8-GHz output. It also achieves 47 fs RMS jitter for a 1.8 GHz output. The LMX2582RHAR supports both fractional-N and integer-N modes, with a 32-bit fractional divider for fine frequency selection.

 

Key electrical characteristics include an input clock frequency up to 1400 MHz and a phase detector frequency up to 200 MHz (or 400 MHz in Integer-N mode). It operates from a single 3.3V power supply and has a typical current consumption of 250 mA. The operating temperature range is -40°C to 85°C.

 

The LMX2582RHAR is available in a 40-VQFN (6x6) package and is designed for surface mount applications.
