NTE1589
Integrated Circuit
Color TV Luminance Chroma System
Description:
The NTE1589 is a multi鈥搊perational integrated circuit in a 28鈥揕ead DIP type package which has all
the necessary functions for video鈥揷hroma: 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鈥搒hoot and over鈥搒hoot can be restrained, and sharp outline correction is available.
D
鈥榝o鈥?adjustment of V
CO
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.
