LMX2541  
Ultra-Low Noise PLLatinum Frequency Synthesizer with  
Integrated VCO  
General Description  
Features  
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 normal-  
ized noise floor of -225 dBc/Hz and can be operated with up  
to 104 MHz of phase-detector rate (comparison frequency) in  
both integer and fractional modes. The PLL can also be con-  
figured to work with an external VCO.

External VCO Option (Internal VCO Bypassed)  
VCO Frequency Divider 1 to 63 (all values)  
Programmable Output Power  
The LMX2541 integrates several low-noise, high precision  
LDOs and output driver matching network to provide higher  
supply noise immunity and more consistent performance,  
while reducing the number of external components. When  
combined with a high quality reference oscillator, the  
LMX2541 generates a very stable, ultra low noise signal.  
Up to 104 MHz Phase Detector Frequency  
Integrated Low-Noise LDOs  
Programmable Charge Pump Output  
Partially Integrated Loop Filter  
The LMX2541 is offered in a family of 6 devices with varying  
VCO frequency range from 1990 MHz up to 4 GHz. Using a  
flexible divider, the LMX2541 can generate frequencies as  
low as 31.6 MHz. The LMX2541 is a monolithic integrated  
circuit, fabricated in a proprietary BiCMOS process. Device  
programming is facilitated using a three-wire MICROWIRE  
interface that can operate down to 1.8 volts. Supply voltage  
ranges from 3.15 to 3.45 volts. The LMX2541 is available in  
a 36 pin 6x6x0.8 mm Lead-Free Leadless Leadframe Pack-  
age (LLP).
