The operation of multiplier and video amplifier circuits used in present TV IF detector ICs is explained. A new detector is described which uses a separate sound detector to allow conventional trapping before the video detector. The sound carrier output is buffered and the video detector features differential inputs and special circuitry to handle input overloads. An NPN video amplifier uses differential to single-ended conversion to improve linearity and dc stability. The 14 lead device also includes an auxiliary video output, a carrier source for AFT, and a sync separator device.
