LMX2571 is the industry's lowest power wideband radio frequency (RF) synthesizer, introduced by Texas Instruments.
The LMX2571 operates up to 1.34 GHz and integrates an ultra-low-noise PLLatinum N frequency-divided phase-locked loop (PLL) and a multi-core voltage-controlled oscillator (VCO) to achieve low phase noise and spurs at only 39mA (128mW). The LMX2571 enhances radio sensitivity and dynamic range and is suitable for applications such as low-power wireless communications, handheld oscilloscopes, and signal analyzers. The integrated frequency modulator enables users to directly modulate the carrier to produce analog frequency modulation (FM) or frequency shift keying (FSK), which benefits portable wireless applications such as land mobile radios, software-defined radios, and wireless microphones.
The LMX2571 is the industry's first integrated RF synthesizer that eliminates integer boundary spurs (IBS), allowing designers to eliminate spurious emissions and maximize the use of radio channels in their wireless systems. The company says engineers can use the LMX2571EVM evaluation module to quickly and easily evaluate the performance of the LMX2571 RF synthesizer.
