DLP7000: 0.7" XGA 2xLVDS NIR technical documentation

Nicholas Caira

Part Number: DLP7000

I am trying to find any/all documentation regarding the use of the 0.7" XGA 2xLVDS NIR using the DLP4100 Disccovery kit. I was told by TI support that the the only documentation for the NIR version would possibly exist in archives from E2E support. Please include all available documentation for the use of said DMD.

Thanks,

Nick

    Hello Nicholas,

    Welcome to the DLP section of the TI-E2E community.

    Unfortunately there was very little documentation on this chip as it was experimental.  It was never a qualified product.  TI support is correct, any information we have would be on E2E.

    As far as the NIR chip it would have the same data sheet as the current DLP7000 other than the illumination and window transmission specifications would be different.

    Hi Fizix,

    Is there any documentation regarding these illumination/transmission specifications? I was able to find some older files specifying some things. Can you look at these and confirm whether these should be suitable for the NIR version?

    Hello Nicholas,

    The first document is one I wrote and the general principles will apply.  The thermal conductivity of the package is the same as in the DLP7000 data sheet.

    As far as incident power, it will be thermally limited like the VIS part.  You can measure the °C rise with 1 W of input power with the thermal solution you are going to use with the mirrors all in the "off" state (assuming you are using the same illumination path as a typical visible illumination system - 24° from the normal and 45° azimuth from the top of the package).  This along with the thermal resistance in the DLP7000 datasheet will give you the array temperature. Then use the array temperature limitation listed in the DLP7000 data sheet.

    The second document shows the window transmission vs wavelength.  This measurement was done with the window used on the experimental NIR 0.7" XGA 2xLVDS DMD.

    The last document is an older document, and are likely modeled values for NIR.

    Beyond this there is no other information to offer.
