LMX2541 Description
The LMX2541 device is an ultra low-noise frequency synthesizer which integrates a high-performance delta-sigma fractional N PLL, a VCO with fully integrated tank circuit, and an optional frequency divider. The PLL offers an unprecedented normalized noise floor of 225 dBc/Hz and can be operated with up to 104 MHz of phase-detector rate (parison frequency) in both integer and fractional modes. The PLL can also be...
