OV530-T64
Enhanced Single-Chip Processor for USB PC Applications

The OV530 CameraMate processor is a low cost enhanced single-chip processor for USB PC camera applications. When combined with an OmniVision SVGA, VGA or CIF digital CameraChip sensor, the OV530 comprises an integrated USB camera system, with no additional USB transceiver or DRAM required. The OV530 also supports audio input for full audio/video operation.

During operation, the OV530 camera interface synchronizes with the CameraChip sensor's YCbCr 422 progressive video data to perform Downsampling, Clamping and Windowing (DCW) functions with the desired resolution requested by users through the USB command set. The embedded Data Compression Engine then compresses the video data and the resultant video data is transferred to the host through the USB interface. This standard USB interface allows the end user to implement PC camera systems easily, rapidly reducing the time-to-market.
