DESCRIPTION  
The LMX2581 is an ultra low noise wideband frequency synthesizer which integrates a delta-sigma fractional N  
PLL, a VCO with fully integrated tank circuit, and an optional frequency divider.  
The LMX2581 integrates several low-noise, high precision LDOs to provide superior supply noise immunity and  
more consistent performance. When combined with a high quality reference oscillator, the LMX2581 generates a  
very stable, ultra low noise signal. The internal VCO can be bypassed so that an external VCO can be used.
