LMX2335数据手册集成电路（IC）的时钟发生器PLL频率合成器规格书PDF

描述 Description

General Description
The LMX2335, LMX2336 and LMX2337 are monolithic, integrated dual frequency synthesizers, including two high frequency prescalers, and are designed for applications requiring two RF phase-lock loops. They are fabricated using National’s ABiC IV silicon BiCMOS process.
