ZHCSA85F August 2012 – February 2019 DLPC410
A typical embedded system application using the DLPC410 controller is shown in Figure 22. The DLPC410, the DMD, and their associated DLP components do not specifically determine the application in which the components are used - customer applications and use cases may vary widely, from Digital Image Lithography to 3D Printing to 3D Scanners using Structured Light. The DMD is capable of being used with multiple illumination source types, from Lasers and LEDs to wide band wavelength mercury halide lamps. The DLPC410 supported DMDs cover applications utilizing ultraviolet (UV), visible, and/or near-infrared (NIR) wavelengths. The duration of each binary pattern displayed on the DMD is totally under control of the Applications Processor. The displayed patterns could be strictly binary patterns or could be bit weight exposures of varying durations representing encoded PWM-based gray scales. The timing of the micromirrors and the illumination sources are controlled at the discretion of a Customer Applications Processor and in many solid state cases, provide best performance when source illuminators are synchronous to the commanded DMD micromirror transitions. The speed, diversity, programmability, and flexibility of the DLPC410 building blocks provide an electro-optical cornerstone for customers to build upon to create applications limited only by customer ingenuity.
In Figure 22, the MBRST 2 signals and the C, D LVDS Data buses are shown with dashed lines to indicate that some DMDs do not require these signals to be used. TI's Reference Design and Evaluation Modules leverage a DLPC410 Controller Board which supports all 5 of the DLPC410 supported DMDs. The performance differences for each application are determined by which DMD Board is plugged into the Controller Board. This provides a single DLPC410 design platform which can then be used for multiple customer SKUs within an application platform for product segmentation purposes.
