CX3: CSI-2 to USB 3.0 Solution for HD Video CSI-2 = Camera Serial Interface v2.0 Sharper Images from a One-Chip Solution: CX3 Powers the World’s Most Advanced HD Video Cameras

HD Video Requires USB 3.0 Bandwidth The market requirements for video cameras are changing Consumers are demanding cameras that support high-definition (HD) video with high image quality HD video requires 1.5-Gbps bandwidth USB 2.0 provides only 480 Mbps and requires compression, which degrades image quality USB 3.0 provides 5 Gbps and delivers high-resolution image quality without the need for compression USB 3.0 delivers high-resolution image quality that today’s consumers demand The USB 3.0 Advantage Bandwidth (Gbps) Bandwidth required for Full-HD (1920 x 1080 @ 30 fps) video Compressed USB 2.0 HD video degrades image quality Uncompressed USB 3.0 HD video delivers the best image quality USB 3.0

Terms You Will Hear Today Bandwidth Bandwidth = # pixels per frame (resolution) x frames per second (frame rate) x # color bits per pixel (color depth) For example, Bandwidth required by 1080p video = 2.07 megapixels x 30 frames per second x 24-bit color = 1.5 Gbps Compression Reduces the Bandwidth requirement of an image using a mathematical algorithm Modifies pixels, degrading image quality Requires an external Compression Engine, usually implemented with FPGA or ASIC CSI-2 (Camera Serial Interface v2.0) A specification that defines the standard data transmission and control interfaces between an image sensor and an image processor Includes a unidirectional serial interface with data and clock signals, and a bidirectional I2C control interface Image Signal Processing (ISP) Algorithms implemented in hardware (FPGA or ASIC) or software to enhance the image quality Mobile Industry Processor Interface (MIPI) Alliance An open membership organization that develops interface specifications for the mobile handset industry Common Video Standards Standard Column Pixels Row Pixels Mega-Pixels Color Depth Frame Rate Bandwidth 1080p 1920 1080 2.07 24 30 1.5 Gbps 720p 1280 720 0.92 664 Mbps VGA 640 480 0.31 16 147 Mbps
