日前,德州仪器(TI)宣布推出了一款业内功耗最低的宽频带射频(RF)合成器LMX2571。该产品集成了具有多内核压控振荡器(VCO)的超低噪声PLLatinumTM分数分频的锁相环(PLL),可覆盖高达1.34GHz的频率范围,并可凭借其低至39mA(128mW)的功耗实现低相位噪声和低杂散。LMX2571提高了低功耗无线通信、手持式示波器以及信号分析仪等应用的无线电灵敏度 Texas Instruments has announced the LMX2571, the industry’s lowest power broadband RF synthesizer. The product incorporates an ultra-low-noise PLLatinumTM fractional-order PLL with a multicore VCO that covers frequencies up to 1.34GHz and enables low-cost, 39mA (128mW) Power consumption to achieve low phase noise and low spurious. LMX2571 Improves Radio Sensitivity for Applications such as Low-Power Wireless Communications, Handheld Oscilloscopes, and Signal Analyzers
