[原创] TI LMX2592低噪音宽带RF锁相环(PLL)解决方案

TI公司的LMX2592是集成了VCO的低噪音宽带RF(20 MHz- 9.8 GHz)锁相环(PLL),支持分数N和整数N模式,6GHz输出的综合噪音49fs,输入频率高达1.4GHz,单电源3.3V工作,主要用在测试/测量设备,防卫和雷达(RADAR),微波骨干网,高速数据转换器的高性能时钟源和卫星通信.本文介绍了LMX2592主要特性,功能框图,应用电路以及评估板LMX2592EVM主要特性和测试建立电路,评估板电路图,材料清单和PCB设计图.

The LMX2592 is a low-noise, wideband RF PLL with integrated VCO that supports a frequency range from 20 MHz to 9.8 GHz. The device supports both fractional-N and integer-N modes, with a 32-bit fractional divider allowing fine frequency selection. Integrated noise of 49 fs for 6 GHz output makes it an ideal low noise source. Combining best-in-class PLL and integrated VCO noise with integrated LDOs, this device removes the need for multiple discrete devices in high performance systems.
