The SN9C2759DM is a webcam controller with better image quality than before because of improved image quality and also the integrated temporal and spatial noise-reduction circuits. It not only brings noise-free image for human eye but also makes the analysis work in machine-vision easier and more robust.

 

The major functions of SN9C2759DM include controlling the CMOS sensor, receiving the image data, converting it to video stream, then sending data to the host via USB. It’s compliant with USB 2.0 High-Speed (HS) and USB Video Class (UVC) 1.1. Compliance with the public standards makes SN9C2759DM easy to be integrated into various fields of application that need high quality video like NB built-in camera, camcorder, surveillance, video conference and machine vision.

 

In video part, SN9C2759DM supports MIPI-CSI2 CMOS sensor interfaces and the resolution of ISP is up to MJPG HD@30fps. Besides the excellent noise-reduction, the new generation ISP is high dynamic range (HDR) design to bring better visual experience. The high performance Motion-JPEG engine and bit rate controller provides various compression ratios to meet bandwidth requirement. This system is controlled by the embedded micro-controller with the built-in statistics of AE / AWB. The flexible architecture includes the mask ROM, internal RAM and external serial-flash which can store the customized codes and parameters.

 

The SN9C2759DM introduces advanced process so that it can keep the power consumption in quite low

level and makes the package as small as possible. There are 3 built-in regulators and no needs of external

oscillator, these features make it able to further save BOM and PCB area. The SN9C2759DM is the best

choice for the compact modern electronic product design.
