Description:
The NTE71115 is a monolithic integrated circuit in a 18–Lead DIP type package designed for use in color television receivers.

Features:
● Positive Video Input: Capacitively Coupled (Source Impedance < 200Ω)
● Adaptive Sync Separator: Slicing Level at 50% of Sync Amplitude
● Internal Vertical Pulse Separator w/Double Slope Integrator
● Output Stage for Vertical Sync Pulse or Composite Sync Depending on the Load; Both are Switched OFF at Muting
● φ1 Phase Control Between Horizontal Sync and Oscillator
● Coincidence Detector φ3 for Automatic Time Constant Switching; Overruled by the VCR Switch
● Time Constant Switch Between Two External Time Constants for Loop Gain; Both Controlled by the Coincidence Detector φ3
● φ1 Gating Pulse Controlled by Coincidence Detector φ3
● Mute Circuit Depending on TV Transmitter Identification
● φ2 Phase Control Between Line Flyback and Oscillator; the Slicing Levels for φ2 Control and Horizontal Blanking can be set Separately
● Burst Keying and Horizontal Blanking Pulse Generation, in Combination with Clamping of the Vertical Blanking Pulse (Three–Level Sandcastle)
● Horizontal Drive Output with Constant Duty Cycle Inhibited by the Protection Circuit or the Supply Voltage Sensor
● Detector for Too Low Supply Voltage
● Protection Circuit for Switching Off the Horizontal Drive Output Continuously if the Input Voltage is Below 4V or Higher than 8V
● Line Flyback Control Causing the Horizontal Blanking Level at the Sandcastle Output Continuously in Case of a Missing Flyback Pulse
● Spot Suppressor Controlled by the Line Flyback Control

Applications:
● Television Receivers
● Video Receivers
