SUBCARRIER  
PHASE–LOCKED LOOP  
The MC44144 is a gated phase–locked loop intended for, but not  
restricted to, video applications. The integrated circuit contains a gated  
phase detector, voltage controlled crystal oscillator, divide–by–4 circuitry,  
and a video clamp. This device provides a 4X reference frequency output,  
and a 1X reference frequency output.  
SEMICONDUCTOR  
TECHNICAL DATA  
The MC44144 is manufactured using Motorola’s high density, bipolar  
MOSAIC process.
