PLL TUNING CIRCUIT  
The MC44871 is a tuning circuit for TV, VCR and Multimedia tuner  
applications. This device contains on one chip all the functions required for  
PLL control of a VCO. This integrated circuit also contains a high frequency  
prescaler and thus can handle frequencies up to 1.3 GHz.  
2
WITH HIGH SPEED I C BUS  
AND 30 V TUNING SUPPLY  
The MC44871 has an integrated dc/dc converter to generate the 30 V  
supply voltage for the tuning amplifier on the chip. A tuner using the  
MC44871 does not require an external 30 V supply.  
SEMICONDUCTOR  
TECHNICAL DATA  
2
The MC44871 is controlled by a I C bus, and has a chip address function.  
The MC44871 data format is the same as the MC44818.  
The MC44871 is manufactured on a single silicon chip using Motorola’s  
high density bipolar process, MOSAIC (Motorola Oxide Self Aligned  
Implanted Circuits).  
16  
• The Pin Called V  
CC2  
for the MC44818 is Now Called CP (Charge  
Pump). This Pin is the Output of the DC/DC Converter; a 1.0 nF  
Capacitor Replaces the Need for an External 30 V Supply
