AL330B-EVB-A0  Digital LCD Display SOC Evaluation Board



The AL330B-EVB-A0 is an evaluation product using AverLogic chips to demonstrate a total solution for Small to Medium Digital LCD Display applications. This EVB product can accept multiple video inputs (Composite video, S-video , Components Video, Analog RGB), which can then be displayed in high quality on an LCD Screen.

The main component is the AL330B chip, a highly integrated Display SOC, containing a 3-Ch + 10-bit ADC, 2D Video Decoder, Deinterlacer, Scaler, Microcontroller, OSD, and TCON. The AL330B can support small to medium Digital TFT-LCD Panels and small to medium AMOLED Display Devices.
This product contains 1 Mbit of serial flash for customizable boot and code storage.

The AL330B is a multi-channel 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 multi-standard 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 and more.

AverLogic can also provide ISP Tools for development and a Converter board for adapting different types of display panels for use with the AL330 EVB. Please contact your representative for more information.
