A TI evaluation module design exists which shows how to connect the DLPC900 controller to the DMD. In creating a new board specific to a customer application, layout guidelines need to be followed to achieve a functional and reliable projection system. To complete the system, an optical module or light engine is required that contains the DLP670S DMD, associated illumination sources, optical elements, and necessary mechanical components. Care must be taken to understand and implement wise design decisions regarding the engineering aspects of illumination and projection optics, digital and analog electronics, software, and mechanical and thermal design principles.
