XS99154-Channel HD/SD Analog Video Decoder

Download

XS9915 is a 4-channel analog composite video decoding chip that supports both HDcctv and CVBS protocols up to 1080P@60fps. XS9915 converts the received high-definition analog composite video signal through analog-to-digital conversion, video decoding, and 2D image processing into YUV format, which is then transmitted to the master chip via the MIPI CSI interface, enabling real- time preview and recording. XS9915 supports bidirectional coaxial audio over video for voice intercom with remote cameras, and also supports bidirectional data communication with camera for remote camera control and firmware upgrades. XS9915 features an embedded audio codec with 5-channel Line-In and 1-channel Line-Out interfaces.
