LC7113 PLL Frequency Synthesizer


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 6 bit BCD binary programmable divide-by-N counter. N-codes are 64+N or 128+N.
