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.
The MC44144 is manufactured using Motorola’s high density, bipolar MOSAIC™ process.
