TV Sync/AGC/Horizontal Signal Processor
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.
