描述 Description

The AU3826 is a media product that is a single chip with cost-effective target for Stand-alone and build-in WEB camera solution. The AU3826 includes Image Signal Processing (ISP) engine, JPEG compression engine and USB 2.0 high-speed controller.The AU3826 is built-in the LDO for Sensor and internal and on-chip clock synthesizer.\r
\r
\r
The AU3826 is a UVC compliance chip with OS support UVC standard (XP SP2/SP3, VISTA SP3, Windows 7 and Windows 8). It can support VGA (300K 640x480) resolution up to 60 fps at JPEG mode or up to 30 fps at YUY2 mode, SXGA (1.3 M, 1280x1024) & Full-HD (2M, 1920x1080) up to 30 fps at JPEG mode.(Full-HD is for parallel I/F only)\r
\r
\r
The AU3826 Built-in 4 regulators for BOM cost and PCB area saving. One regulator is designed to convert 3.3V source-in to 1.1V-to-2.9V adjustable power out for sensor. And, the other one regulator is designed to convert 3.3V source-in to 1.1V-to-1.9V adjustable power out for sensor. Another one regulator is designed to convert 3.3V source-in to 1.2V and 1.8V for AU3826 core power and interface power.\r
\r
\r
With on-chip clock synthesizer, AU3826 is allowed to be programmed as various set of clock speed for performance and power saving. Additional clock output with various clock speed ranged up to 144MHz is provided for video capture module.
