Video signal processor for eith B﹠W or color TV The chip contains a keyed AGC amplifier that provides forward AGC voltage for video IF amplifiers and tuners equipped with NPN bipolar transistors. It provides compdsite sync outputs with positive and negative going signals. There's also reverse AGC voltage for tuners equipped with MOSFETs, PNP bipolar transistors, or tubes in the BF stage. The video output is a low-impedance emitter follower. In addition there's a preset noise detector for gating the chip's sync separator and AGC detector (courtesy GTE Sylvania Incorporated).
