Introduction
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.
