NTE1673
Integrated Circuit
Video Chroma Processor
Description:
The NTE1673 is a multifunctional integrated circuit in a 28鈥揕ead DIP type package where an APC
chroma circuit is formed so compactly as to use only 16 pins with the characteristic requirements re-
maining fulfilled and the rest of pins are used for video circuits. It contains a double doefferential circuit
enabling soft video tone, a color temperature control circuit enabling reproduction of beautiful bright
white color and true color, and a high level contrast circuit elinimating brightness drop at the time of
contrast adjustment, thereby allowing a wider design margin for television set design engineers.
