LMX2502/LMX2512 Frequency Synthesizer System with Integrated VCO June 2003 LMX2502/LMX2512 PLLatinum™ Frequency Synthesizer System with Integrated VCO General Description LMX2502 and LMX2512 are highly integrated, high performance, low power frequency synthesizer systems optimized for Korean PCS and Korean Cellular CDMA (1xRTT, IS-95) mobile handsets. Using a proprietary digital phase locked loop technique, LMX2502 and LMX2512 generate very stable, low noise local oscillator signals for up and down conversion in wireless munications devices. LMX2502 and LMX2512 include a voltage controlled oscillator (VCO), a loop filter, and a fractional-N RF PLL based on a delta sigma modulator. In...
