MOTOROLA ANALOG IC DEVICE DATA
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.
