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.
