Averlogic’s AL330B is a highly integrated display SoC, containing a 3-channel 10-bit ADC, 2D video decoder, deinterlacer, scaler, microcontroller, OSD and TCON.

The chip can support small to medium digital TFT-LCD panels and AMOLED display devices.

The device is a multichannel analog pre-processing 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; and a digital RGB signal output.

Applications cover in-car TV/GPS/navigation and entertainment display systems, video door phones, baby monitors and digital photo frames.
