/Fast RGB Blanking
Description:
The NTE7048 is a monolithic integrated decoder for the NTSC color television standard. This device
combines all functions required for the identification and demodulation of NTSC signals ina 20–Lead
DIP type package. Furthermore, it contains a luminance amplifier, an RGB–matrix and amplifier.
These amplifiers supply output signals up to 5V
P–P
(Picture information) enabling direct drive of dis-
crete output stages.
Features:
Automatic Chrominance Leveling (Avoids Saturation at the Chrominance Input)
Peaking Circuit with DC Control
Fast RGB Output Blanking
