FEATURES  
DESCRIPTION  
LMX2542 is a highly integrated, high performance,  
low power frequency synthesizer system optimized  
for Cellular-CDMA 1xRTT and IS-95 mobile handsets  
and data systems with GPS capabilities. Using a  
proprietary digital phase locked loop technique,  
LMX2542 provides very stable, low noise local  
oscillator (LO) signals for up and down conversion in  
wireless communications devices.

N RF PLL Based on 11-Bit ΔΣ Modulator  
LMX2542 includes a Voltage Controlled Oscillator  
(VCO) for both the Cellular-CDMA and GPS  
frequency bands, a loop filter, and a Fractional-N RF  
PLL based on a Delta Sigma (ΔΣ) modulator. In

•
IF Synthesizer System  
LMX2542 includes an Integer-N IF PLL also. For  
more flexible loop filter designs, the IF PLL includes a  
4-level programmable charge pump. Together with an  
external VCO and loop filter, LMX2542 makes a  
complete closed loop IF synthesizer system. The  
default IF frequency is 367.20 MHz.
