For connecting together the XC7Z020-1CLG484I4493 FPGA, the two DLPC3437 controllers, the DLPA3000/DLPA3005, and the DLP3310 DMD, see the reference design schematic. When a circuit board layout is created from this schematic a very small circuit board is possible. An example small board layout is included in the reference design data base. Layout guidelines should be followed to achieve a reliable projector.

The optical engine that has the LED packages and the DMD mounted to it is typically supplied by an optical OEM who specializes in designing optics for DLP projectors.
