NTE818
Integrated Circuit
TV Luminance Processor
Features:
Luma/Chroma Tracking
Automatic Beam Limiter
DC Restoration
Luma/Chroma Vertical Blanking
Single DC Gain Control
Low External Component Count
Description:
A single DC picture control adjusts the gain of both the low–level video and chroma amplification in
color TV receivers which employ the NTE818Luminance Processor. Automatic brightness limiting
(ABL) and vertical maintaining a constant black level. During the horizontal blanking interval, the
black level is determined by clamping the black–level reference (the “back porch”). This allows for
100% DC restortion.
