NTE7115

NTE7115 Integrated Circuit Color TV Horizontal Combination Circuit Description: The NTE71115 is a monolithic integrated circuit in a 18–Lead DIP type package designed for use in color television receivers. Features: D Positive Video Input: Capacitively Coupled (Source Impedance < 200Ω) D Adaptive Sync Separator: Slicing Level at 50% of Sync Amplitude D Internal Vertical Pulse Separator w/Double Slope Integrator D Output Stage for Vertical Sync Pulse or Composite Sync Depending on the Load; Both are Switched OFF at Muting D ö1 Phase Control Between Horizontal Sync and Oscillator D Coincidence Detector ö3 for Automatic Time Constant Switching; Overruled by the VCR Switch D Time Constant Switch Between Two External Time Constants for Loop Gain; Both Controlled by the Coincidence Detector ö3 D ö1 Gating Pulse Controlled by Coincidence Detector ö3 D Mute Circuit Depending on TV Transmitter Identification D ö2 Phase Control Between Line Flyback and Oscillator; the Slicing Levels for ö2 Control and Horizontal Blanking can be set Separately D Burst Keying and Horizontal Blanking Pulse Generation, in Combination with Clamping of the Vertical Blanking Pulse (Three–Level Sandcastle) D Horizontal Drive Output with Constant Duty Cycle Inhibited by the Protection Circuit or the Supply Voltage Sensor D Detector for Too Low Supply Voltage D Protection Circuit for Switching Off the Horizontal Drive Output Continuously if the Input Voltage is Below 4V or Higher than 8V D Line Flyback Control C...
