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 VCO is available by variable resister 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.
