LC7110 PLL Frequency Synthesizer

Overview

This 27 MHz band, PLL frequency synthesizer LSI chip is designed specifically for CB transceivers. The integrated circuit`s incorporates PLL circuitry and a controller for CB applications on a single CMOS chip.
This PLL-circuit use a 9 bit ROM programmable divide-by-N counter to divide from N=150 to N=194. The ROM-table is programmed from factory to 40 channels CEPT.
