www.ti.com SNWS009B – MARCH 2003 – REVISED APRIL 2013 LMX2522/LMX2532 PLLatinum™ Frequency Synthesizer System with Integrated VCOs
Check for Samples: LMX2522, LMX2532 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. 1 23 Small Size
