LMX2541 Datasheet High Performance Frequency Synthesizer System

Manufacturer: National Semiconductor Corporation

Overview: LMX2541 Ultra-Low Noise PLLatinum Frequency Synthesizer with Integrated VCO ..

General Description

The LMX2541 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 configured to work with an external VCO.
