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
