1 / 6 page 8-42 May 1999 CA3154 TV Sync/AGC/Horizontal Signal Processor Features • Horizontal Oscillator with AFC • Sync Separator with Noise Immunity • Strobed AGC System • lF AGC Output • Delayed Outputs for Forward or Reverse AGC Tuners • Internal Noise Threshold • High-Impedance Video Input • Choice of Dual External Time Constants for Sync Separator Noise Immunity • RF AGC Delay Externally Controlled • Output Short-Circuit Protection 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.
