I haven't had any response to this same question in the TI Designs Forum, so am posting here.
I notice that you provide CAD files for a 4K DLP Reference design, based on the DLP660TE. However, these files appear to be in .DXF format, which isn't particularly useful for electronics design. Would it be possible to get the schematics/Layout in Altium (Preferable) or Orcad formats? Orcad (.dsn) design files are currently available for the DLP4500-C350REF Reference Design.
