8.2.1 Design Requirements

A high-accuracy 3D depth scanner product can be created by using a DLP chipset comprised of DLP3010 DMD, DLPC3478 controller and DLPA200x or DLPA300x PMIC/LED driver. The DLPC3478 simplifies the pattern generation, the DLPA200x or DLPA300x provides the needed analog functions and the DMD displays the required patterns for accurate 3D depth scanning.

In addition to the three DLP devices in the chipset, other IC components may be needed. At a minimum, this design requires a flash device to store the software and firmware to control the DLPC3478 .

Red, green, and blue LEDs typically supply the illumination light that is applied to the DMD. These LEDs are often contained in three separate packages, but sometimes more than one color of LED die may be in the same package to reduce the overall size of the pico-projector. In addition to LEDs, other light sources like laser diodes, vertical-cavity surface-emitting laser (VCSEL) are also supported.

The parallel interface connects the DLPC3478 controller to the host processing for receiving patterns or video data. Connect an I2C interface to the host processor to send commands to the DLPC3478 controller. The battery (SYSPWR) and a regulated 1.8-V supply are the only power supplies needed external to the projector in case of DLPA200x. The DLPA300x supplies 1.8 V without external regulator. A single signal (PROJ_ON) controls the entire DLP system power. When PROJ_ON is high, the DLP system turns on and when PROJ_ON is low, the DLPC3478 turns off. When the DLPC3478 is off, the DLP system draws only a few microamperes of current on SYSPWR. When PROJ_ON is low, the 1.8-V power supply can remain at 1.8 V for use by other sub systems. When PROJ_ON is low, the DLPA200x or DLPA300x draws no current on the 1.8-V supply.
