NTE1589
Integrated Circuit
Color TV Luminance Chroma System
Description:
The NTE1589 is a multi–operational integrated circuit in a 28–Lead DIP type package which has all
the necessary functions for video–chroma: such as second differential video tone control circuit (DC
controlling available), contrast control, pedestal clamp, brightness adjustment circuit, video blanking
circuit, BPA amplifier (peak detection shaped ACC detector), color synchronizer (APC type), and color
recovery (color difference output).
Characteristics:
D Because of its second differential video tone control method of current amplifying type, amplitude
of pre–shoot and over–shoot can be restrained, and sharp outline correction is available.
D ‘fo’ adjustment of V
D Because of its color difference output, frequency response of video amplifier is very good.
D Because its control is all D.C. controlling, remote control is available.
