1. Introduction
1.1. Introduction
AL320C is an Analog LCD Display Controller which is a combination of a multi-
channel analog preprocessing circuit including source selection, anti-aliasing filter
and ADC, ACC (Auto-Clamp Control) and AGC (Auto-Gain Control), CGC (Clock
Generation Circuit), digital multi-standard decoder containing chrominance and
luminance separation by an adaptive 2D comb filter, a brightness, contrast, hue and
saturation control circuit, programmable horizontal and vertical scalar, image and
sharpness enhancement processing, On-Screen-Display, programmable Tcon and 3-
Channel DAC outputs, etc.
