NTE1416
Integrated Circuit
Chrominance and Luminance Processor for
NTSC Color TV
Description:
The NTE1416 is an MSI integrated circuit in a 28Lead DIP type package designed for NTSC systems
to process both color and luminance signals for color televisions. This device provides two functions:
The processing of color signals for the band pass amplifier, color synchronizer, and demodulator cir-
cuits and also the processing of luminance signal for the luminance amplifier and pedestal clamp cir-
cuits. The number of peripheral parts and controls can be minimized and the manhours required for
assembly can be considerbly reduced.
Features:
D
Few External Components Required
D
DC Controlled Circuits make a Remote Controlled System Easy
D
Protection Diodes in every Input and Output Pin
D
"Color Killer" Needs No Adjustements
D
"Contrast" Control Does Not Prevent the Natural Color of the Picture, as the Color Saturation
Level Changes Simultaneously
D
ACC (Automatic Color Controller) Circuit Operates Very Smoothly with the Peak Level Detector
D
"Brightness Control" Pin can also be used for ABL (Automatic Beam Limitter)
