The AL330B from AverLogic is a highly integrated display SoC (system-on-chip) containing a 3-channel 10-bit ADC, 2D video decoder, deinterlacer, scaler, microcontroller, OSD and TCON. The device can support small to medium digital TFT-LCD panels and small to medium AMOLED display devices.

The AL330B is a multichannel analog preprocessing circuit which includes source selection; anti-aliasing filter; ADC, ACC (auto-clamp control) and AGC (auto-gain control); CGC (clock generation circuit); digital multistandard decoder containing chrominance and luminance separation from an adaptive 2D comb filter; brightness, contrast, hue and saturation control circuit; programmable horizontal and vertical scaler; image and sharpness enhancement processing; on-screen display; programmable TCON; and a digital RGB signal output.
