Hello,

Thank you for using the DLP E2E forums.

The DLPC4422 controller is capable of supporting the different data formats mentioned in the datasheet.
Unfortunately with the available firmware and DLPC4422 GUI 1.0, the EVMs are set to only accept RGB data.

As it is now, you are not able to change this setting with the provided GUI.

Regards,
Oscar

Xing,

This reference design, TIDA-01474, will provide with all need you for the main controller board.
The design uses the 0.47 1080p DMD board but it will also work with the DLP650NE as long as you use the correct firmware.

Oscar

Hi,

Ti.com dlp650ne firmware is set to accep RGB data. Is it single channel 30 bits RGB888 Input( or 10 bits per color) or double channel 60 bits RGB888 Input( or 10 bits per color)? It is very important to my hardware design.

The TI.com firmware is configured for single pixel.
But can be changed via the GUI.
