描述 Description

The RTS5825-VC is a USB 3.0 compliant camera controller designed for notebook and desktop PCs. The built-in extremely low-power transceiver provides superior compatibility with USB hosts and high quality for image applications. It is fully compliant with the USB Video Class, and operates with native drivers provided in Windows XP, Windows Vista, Windows 7, and Windows 8 operating systems.
The RTS5825-VC integrates a USB 3.0 transceiver that is optimized for high performance data transfer rate, high speed MCU (Micro Processor Unit), DC-to-DC regulators, sensor controller, image signal processing engine, and MJPEG compression into a single chip. It supports most available CMOS sensors from VGA (640x480) to QXGA (2048x1536) resolution.
The RTS5825-VC is designed to provide both an MIPI CSI-2 two-lane data interface, and a classic parallel interface for the CMOS image sensors. It offers the flexibility to support image sensors provided by various sensor vendors.
A new generation ISP (Image Signal Processing) engine supports most UVC defined image adjustments. In addition, this engine also has offers functions such as Lens Shading Correction, dead pixel cancellation, G1G2 filter, Color Correction Matrix, histogram statistic Auto White Balance, scaling function and so on. These functions help compensate for intrinsic inaccuracy in lens and image sensors to provide better image quality. The internal scaling filter can scale down higher resolutions for size reduction purposes.
The RTS5825-VC integrates five regulators to save BOM cost and PCB area. One 5V-to-3.3V regulator converts USB bus power to 3.3V power for device I/O. Two 3.3V-to-1.2~3.1V adjustable regulator converts 3.3V to 1.2~3.1V for the sensor’s IO and analog power. Two 3.3V-to-1.2V regulators convert 3.3V power to 1.2V core power for the RTS5825-VC. 
A significant feature of the RTS5825-VC is enhanced power management. Its power consumption is 20% lower than similar controllers. With multiple regulators, an integrated image signal processing engine and motion JPEG encoder, the RTS5825-VC consumes less power from the USB bus whether in normal operation, standby, or suspend mode.
