SN9C2805A Datasheet规格书参数PC Camera Controller
The SN9C2805A is a high resolution webcam controller. Besides improved image quality, this generation of ISPsupports wide dynamic range (WDR) and vertical lens distortion correction (VLDC) to bring better visual
experiences. It not only brings less noise image for human eye but also makes the analysis work in machine-vision
easier. For modern high resolution and AI applications, SN9C2805A would be a higher performance and cost
effective choice.
Besides video ISP, SN9C2805A also supports UAC 1.0 specification which records audio form I2S interface or
digital microphone input. Programmable audio sampling frequency from 8KHz to 48KHz and resolution of 8/16 bit
with mono or stereo.
The major functions of SN9C2805A include controlling the CMOS sensor, receiving the image data, converting it to
video stream, and then sending data to the host via USB. It’s compliant with USB 2.0 High-Speed (HS) and USB
Video Class (UVC) 1.1/1.5 over ISO or Bulk in transfer. Compliance with the public standards makes SN9C2805A
easy to be integrated into various fields of applications that need high quality video like high resolution tablet built-in
camera, camcorder, surveillance, video conference and machine vision (AI).
SN9C2805A supports both parallel and MIPI-CSI2 1/2-lane CMOS sensor interfaces and the performance of ISP is
up to 2592x1944@30fps or up to 1920x1080@60fps. 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.
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 SN9C2805A is the best choice for the compact modern electronic product design.
