LMX2502 Datasheet (National Semiconductor) - Frequency Synthesizer System

LMX2502, Frequency Synthesizer System

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 os
