LMX2541 Ultra-Low Noise PLLatinum Frequency Synthesizer With Integrated VCO Features 3 DescriptionThe LMX2541 deviceis an ultra low-noise frequency Multiple Frequency Options Available synthesizer which integratesa high-performance(See Device Comparison Table) delta-sigma fractional N PLL,a VCO with fully• Frequencies From 31.6 MHzto 4000 MHz integrated tank circuit, and an optional frequency Very Low RMS Noise and Spurs divider. The PLL offers an unprecedented normalized
noise floorof –225 dBc/Hz and can be operated with• –225 dBc/Hz Normalized PLL Phase Noise upto 104 MHzof phase-detector rate (comparison• Integrated RMS Noise (100 Hzto20 MHz) frequency)in both integer and fractional modes. The– 2 mRad (100 Hzto20 MHz)at 2.1 GHz PLL can also be configuredto work with an external
