DLPLCRDC4422EVM: NEED THE FRONT END BOARD TO INTERFACE WITH DLPC4422 (2x)

Alpesh Borad

Part Number: DLPLCRDC4422EVM

Hello,

I am going to design the 4K UHD projector using DLPLCRDC4422EVM and DLP660TEEVM.

I have searched for the front end board which will be connected with the DLPLCRDC4422EVM but not found.

I need the help to select the Front End Board which has HDMI and other basic Input interface and connect with the DLPLCRDC4422EVM Board.

Also suggested light source compatible with this set up.

Kindly suggest the best options for the front end board for DLPLCRDC4422EVM.

Regards,

Alpesh.

    Alpesh,

    At the moment, there is no front-end interface board that we can publicly recommend.  What we can recommend at the moment is to reach out to companies such as iChips, M-Star, ITE and other like front-end manufactures for a product that is compatible with our EVM. 

    The Firmware package for each of the DMD EVMs associated with the DLPLCRDC4422EVM has an xls file with the recommended and alternate Vx1 video input timings.  

    DLP470TE-FW: DLPC4422 Controller support firmware for DLP470TE DMD

    DLP660TE-FW: DLPC4422 Controller support firmware for DLP660TE DMD

    Please note that the the V-By-One input is 8 lanes with a 600MHz pixel clock.  It is important to take this into consideration when choosing a source.  Many of them do not specify the V-By-One pixel clock.  

    There are a few more details in this post.

    Regards,

    Hello Gary,

    Thanks for the Details.

    I have some questions as mentioned below.

    Option 1: - Make connection between two EVM - DLPLCRDC4422EVM and DLP660TEEVM. Front-end interface board  is not Connected.

    1) Can I able to get/show the Image at the DLP660TEEVM?

    2) In this case, How can I get the output Image from the DLP660TEEVM?

    3) What is input image source for this configuration (RS-232, HDMI, DVDI etc...)?

    4) How can I get the display Image without the front-end interface board?

    My main concern is that If I am unable to find any front-end interface board then what is the Input image source for this configuration to start the Projector and How can I start the projector without front-end interface board?

    Kindly suggest the best option at this stage to kick off the project of the projector.

    Regards,

    Alpesh.

    Alpesh,

    The EVM does not require a "front end" to run.  For internal development and bench work, we control the projector over USB via the DLPC4422 GUI (Windows).  This GUI can be downloaded here: https://www.ti.com/tool/DLP660TE-SW.  One needs the DLPC4422 GUI as well as files from the FW package. Please see the EVM User's Guide for details.

    In an end-product, the customer designs their own front end with whatever inputs they require for their product.  The front end generally includes some kind of microprocessor to control the DLPC4422 over USB or I2C.  Information on controlling the DLPC4422 is included in the DLPC4422 Software Programmer's Guide, which is included in the DLP660TE Firmware download.  This guide details the commands supported by the DLCP4422 embedded software.

    For testing the EVM/DMD interface, there is an internal test pattern generator (TPG) that can generate a few basic test patterns.  The built-in TPG cannot display live video or custom images. 

    The EVM can also display a basic fixed "Splash Image" on the DMD.  Instructions on how to display this built-in image are included in the EVM User's Guide.

    The built-in splash image as well as the basic built-in test patterns can be displayed using the GUI mentioned previously (i.e. no front-end board or V-by-one input required).

    The only live video input to the DLPLCRDC4422EVM is V-by-one HS; the video timings supported are in the XLS files I referred to in my previous post.  An FPGA on the EVM does video processing and converts the V-by-one input to the 60-bit inputs required for each of the two DLPC4422 controllers on the EVM.  To input live video to the EVM, you will need to find a source that provides V-by-one.  Some comments on this are in this post.

    Regards,
    Gary
