Description

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.
