For connecting the DLPC4430 display controller and the DLP550JE DMD, see the reference design schematic. For a complete DLP system, an optical module or light engine is required that contains the DLP550JE DMD, associated illumination sources, optical elements, and necessary mechanical components. The optical module is typically supplied by an OMM (optical module manufacturer) who specializes in designing optics for DLP projectors.

To ensure reliable operation, the DLP550JE DMD must always be used with the DLPC4430 display controller, a DLPA100 PMIC driver, and a DLPA200 DMD micromirror driver.
