AL330B-EVB-A1  Digital LCD Display SOC Evaluation Board

 


Introduction

The AL330B-EVB-A1 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, and Components video), 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.
