Overview

Order this document by MC44864/D Advance Information PLL Tuning Circuit with 1.
3 GHz Prescaler and D/A Converters for Automatic Tuner Alignment The MC44864 is a tuning circuit for TV applications.
This device contains a PLL section and a DAC section and is MCU controlled through an I2C Bus.
The PLL section contains all the functions required to control the VCO of a TV tuner.
The IC generates the tuning voltage and the additional control signals, such as band switching voltages.
The D/A section generates three additional varactor voltages to feed all of the varactors of the tuner with individually optimized control voltages (automatic tuner adjustment).
The MC44864 is manufactured on a singl...
