日前,德州仪器(TI)宣布推出支持高级频率调制功能的业界最高性能14 GHz分数N分频PLLatinum 锁相环(PLL)。该LMX2492提供业界最佳噪声性能,比性能最接近的同类竞争器件低6 dB,可提升射频(RF)灵敏度以及雷达覆盖范围及精确度。此外,该器件还支持200 MHz的相位频率检测器、5V充电泵电源以及500 MHz至14 GHz的宽泛工作频率。LMX2492提供工业及汽车级(1级)版本,适用于军事与汽车雷达、微波回程、通信以及测量测试应用。
Texas Instruments (TI) today announced the industry’s highest performance 14 GHz fractional-N PLL PLL (TM) PLL (phase-locked loop) PLL supporting advanced frequency modulation. The LMX2492 offers the industry’s best noise performance, 6 dB lower than competing devices of the closest performance, improving RF sensitivity and radar coverage and accuracy. In addition, the device supports 200 MHz phase frequency detector, 5V charge pump power supply and 500 MHz to 14 GHz wide operating frequency. The LMX2492 is available in industrial and automotive (Level 1) versions for military and automotive radar, microwave backhaul, communications and measurement test applications.
