STV8211 VIDEO & SOUND IF SYSTEM . . . . . . . . . . ADVANCE DATA VERY LOW CURRENT ABSORPTION 3 STAGE IF GAIN CONTROLLED AMPLIFIER SYNCHRONOUS VIDEO DEMODULATOR WHITE SPOT AND NOISE INVERTER AGC CIRCUIT WITH NOISE GATING TUNER AGC OUTPUT FOR PNP TUNERS FM DETECTOR AF AMPLIFIER WITH DC VOLUME CONTROL AFC 2 VPP ON VIDEO OUTPUT DIP20 (Plastic Package) DESCRIPTION The STV8211 is a monolithic integrated circuit in DIP20 package for black & white television receivers using PNP tuners. It is intended to operate with a negatively modulated vision carrier and frequency modulated sound carrier. Used with TEA2037A (H/V deflection circuit), this IC permits a complete low-cost solution for black and white applications.
