Integrated Circuit  
NTSC Decoder for TV  
Description:  
The NTE1890 is a monolithic integrated decoder for the NTSC color television standards. It combines  
all functions required for the demodulation of NTSC signals. Further more it contains a luminance  
amplifier, an RGB–matrix and amplifier. These amplifiers supply output signals up to 5V peak–to–  
peak (picture information) enabling direct drive of the discrete output stages.
