Technical Principle: EM2860 ,EM2828X is a highly integrated video bridge chip that includes an analog video decoder (supporting CVBS and S-Video inputs), a USB 2.0 controller, and a video processing engine. Its core function is to digitize analog video signals and transmit them to the host through a USB interface without the need for an additional acquisition card.

Architecture Description

The chip adopts a three-layer architecture consisting ofAnalog Front End (AFE), video processing, and USB interface. Simulate front-end to complete video signal clamping, gain, and A/D conversion; The video processing module performs color space conversion, scaling, and de interlacing processing; The USB interface is responsible for communicating with the host. The overall power consumption is controlled at a low level, suitable for embedded and portable devices.

Key parameters (qualitative)

Support input resolution: standard definition to high definition (non 4K);

; Output frame rate: standard frame rate (non high frame rate); Working temperature: commercial grade range; Power consumption: low. For more detailed parameters, it is recommended to consult the manufacturer for the latest specifications.

Selection suggestion

If the project has high requirements for power consumption and compatibility, and the video source is standard definition or ordinary high definition (not 4K), EM2860 is a mature and reliable solution.. If needed 4K@60fps Or ultra-low latency, it is recommended to evaluate the EM37180 series or other USB 3.0/PCIe solutions with higher bandwidth from Video End Technology. During the development process, please refer to the official reference design and consult the manufacturer for the latest drivers and specifications.
