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:
Positive Video Input: Capacitively Coupled (Source Impedance < 200
)
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
1
Phase Control Between Horizontal Sync and Oscillator
Coincidence Detector
3
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
3
1
Gating Pulse Controlled by Coincidence Detector
3
Mute Circuit Depending on TV Transmitter Identification
2
Phase Control Between Line Flyback and Oscillator; the Slicing Levels for
2
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
