EZ-USB™ CX3 Programmable MIPI CSI-2 to USB 3.0 Camera Controller

Overview

Add USB 3.0 connectivity to image sensors with MIPI CSI-2 interface

Infineon EZ-USB™ CX3 enables USB 3.0 connectivity to any image sensor which is compliant with Mobile Industry Processor Interface (MIPI) Camera Serial Interface Type 2 (CSI-2) standard. Based on the proven EZ-USB™ FX3 Platform, CX3 includes a fully accessible ARM9 CPU and 512 KB SRAM that provides 200 MIPS of computational power. CX3 also supports Camera Control Interface (CCI) for image sensor configuration. CX3's multiple peripheral interfaces such as I²C, SPI, and UART can be programmed to support pan, tilt and zoom or other camera control functions.
