FEATURES  
DESCRIPTION  
LMX2522 and LMX2532 are highly integrated, high  
performance, low power frequency synthesizer  
systems optimized for Korean PCS (K-PCS) with  
GPS and Korean Cellular (K-Cellular) with GPS,  
CDMA (1xRTT, IS-95) mobile handsets. Using a  
proprietary digital phase locked loop technique,  
LMX2522 and LMX2532 generate very stable, low  
noise local oscillator signals for up and down  
conversion in wireless communications devices.

Modulator  
LMX2522 and LMX2532 include  
a RF voltage  
controlled oscillator (VCO), a GPS VCO, a loop filter,  
and a fractional-N RF PLL based on a delta sigma  
modulator. In concert these blocks form a closed loop  
RF and GPS synthesizer system. LMX2522 supports  
the Korean PCS band with GPS and LMX2532  
supports the Korean Cellular band with GPS.
