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 < 200)
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 Causing the Horizontal Blanking Level at the Sandcastle Output Continuously
in Case of a Missing Flyback Pulse
D Spot Suppressor Controlled by the Line Flyback Control
Applications:
D Television Receivers
D Video Receivers
