EM28281 is a highly integrated USB 2.0 CVBS video capture chip that integrates Video ADC (Analog Video Decoder), Audio ADC (Analog Audio Encoder), and USB 2.0 controller into a single chip. It can directly connect to CVBS analog cameras and output UVC+UAC drive free digital audio and video streams.
Core Features:
- Highly integrated: Single chip built-in 10 bit Video ADC+Audio ADC+USB 2.0 PHY
- Video input: CVBS composite video (NTSC/PAL automatic detection)
- Resolution: D1 (720 × 480 NTSC/720 × 576 PAL)
- Audio: Mono analog audio input, UAC standard protocol
- Output interface: USB 2.0 High Speed, UVC+UAC drive free
- Packaging: Small volume QFN, suitable for compact product design
- Comparative advantage: Compared to the EM2860+external Video ADC solution, the BOM cost is lower and the PCB area is smaller
Typical application:
- Car rearview/reverse camera acquisition
- USB Video Capture Stick (CVBS to USB)
- Industrial endoscope and pipeline inspection
- Digital upgrade of analog camera
- Security monitoring DVR USB acquisition module
Pingti suggestion: It can replace the EM2860+Video ADC two chip solution, with fully compatible drivers.
