LMX2512数据手册开发板套件编程器的评估演示板及套件规格书PDF

描述 Description

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 communications devices.
