• Horizontal Oscillator with AFC

• Sync Separator with Noise Immunity

• Strobed AGC System

The CA3154 is a monolithic integrated circuit TV signal

processor designed for use in color or monochrome

receivers. Circuit functions include a horizontal oscillator with

AFC, a sync separator, and a keyed AGC system. The AGC

system provides output signals for IF (reverse) and tuner

(forward and/or reverse). The wide frequency-range

horizontal oscillator has high stability at 503.5kHz. When the

CA3154 is used in conjunction with horizontal/vertical

countdown circuits, the need for horizontal and vertical hold

controls is eliminated.
