LMX2581EVAL/NOPB

FREQUENCY SYNTHESIZER, EVALUATION MOD.

The LMX2581EVAL/NOPB evaluation module helps designers evaluate the operation and performance of the LMX2581 wideband frequency synthesizer which integrates a delta sigma fractional NPLL, 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.
