PLL TUNING CIRCUIT  
WITH 1.3 GHz PRESCALER  
AND D/A CONVERTERS  
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 I C Bus.  
2
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 single  
silicon chip using Motorola’s high density bipolar process, MOSIAC  
(Motorola Oxide Self–Aligned Implanted Circuits).
