DLP6500FLQ: questions on the hardware development

Charles Liang
Prodigy 30 points
Part Number: DLP6500FLQ
Other Parts Discussed in Thread: DLPLCR65FLQEVM, DLPLCRC910EVM, DLPC910, DLPLCR65EVM, DLPLCRC900EVM, DLPC900, DLP6500FYE, DLP9000X, DLP9000

Hi Team,

My goal is to make my chip DLP6500FLQ functional and controllable by PC. Could you please suggest all the options I have for the hardware development?

Right now, I only have a single chip DLP6500FLQ (www.ti.com/.../DLP6500FLQ. In order to make it functional and controlable by PC, do I need to add an EVM to make it become DLPLCR65FLQEVM (www.ti.com/.../DLPLCR65FLQEVM Or can the DLPC910 controller alone fulfill the purpose, and which should I get, DLPC910 or DLPLCRC910EVM? 

Thanks,

Charles

    Hello Charles,

    To operate a DLP6500FLQ we offer the DLPLCR6500FLQEVM, which comes with a DMD in it.  It needs a controller EVM in this case the DLPLCRC910EVM and if you wish to use the matching APPS_FPGA code as is you will need to obtain a Virtex VC-707 EVM to drive the DMD and communicate with a PC.

    It is possible to use a different FPGA board to feed the DLPLCRC910EVM board, but you will need to adapt the provided APPS_FPGA source code to match the FPGA board you choose.

    It is possible to design your own controller board and even DMD board, but I recommend using the TI EVMs as a starting point, but we do have reference schematics with BOMs.

    I hope this helps.

    Hi Fizix,

    Thank you for your reply.

    So for my purpose of controlling the DMD, I will need both DLPLCR6500FLQEVM and DLPLCRC910EVM correct? Right now, I have a single chip DLP6500FLQ, is there an easy way to make it to be DLPLCR6500FLQEVM? If not, can I return the DLP6500FLQ (fresh new and never used) and purchase DLPLCR6500FLQEVM instead?

    What are APPS_FPGA code and Virtex VC-707 EVM? Can you send me more info/links for those? Are they used for software control of DMD? Could the DLPLCRC910EVM and DLPC910REF-SW enable the software control? 

    Thanks,

    C

    Hello Charles,

    As far as returning the DMD, you will have to take that up with the vendor you purchased it through.  If it was ti.com then you will need to contract them directly.  I do not think you can purchase a DLPLCR6500FLQEVM sans the DMD.

    The DLPLCRC910 does not have patterns built into it.  The APPS_FPGA code runs on an external FPGA - in the case of a Xilinx VC-707 EVM it is a Virtex 7.  That code generates patterns to send to the DLPC910 controller on a DLPLCRC910 EVM.  The FMC connectors on the DLPLCRC910EVM are made to mate to the FMC connectors on a Xilinx VC-707 EVM board.

    The APPS_FPGA code and other information can be found here:

    Hi Fizix,

    Thank you very much for all the information. Could you send me a link or suggest how I can purchase the Xilinx VC-707 EVM board? I couldn't find it on TI website. 

    Also, I found in your previous forum (DLP6500FLQ: Selection of Controller and Evaluation Board: DLPC900 or DLPC910? - DLP products forum - DLP®︎ products - TI E2E support forums), you mentioned that DLPC900 controller has pattern memory and is compatible with DLPLCR65EVM for the DLP6500FYE DMD. Does that mean I can get DLPLCR65EVM + DLPLCRC900EVM and those two can enable PC control of the DMD? If so, what are the major differences in performance and use comparing that combination with DLPLCR6500FLQEVM + DLPLCRC910EVM + Xilinx VC-707 EVM? 

    Thanks,
    C

    Charles,

    If you are able to use the non-hermetic DLP6500FYE DMD then you can get a DLPLCR65EVM which has a DLP6500FYE DMD on it and is designed to mate via a special flex cable to a DLPLCRC900EVM.

    I the case of the DLPC900 controller based EVM, no other hardware other than the DMD EVM and controller EVM are needed to control it from a PC.

    Regarding the Xilinx VC-707 EVM, that is a Xilinx product and ti.com does not sell it.  You will have to check with retailers like Digikey, Mouser, Newark, etc . . .

    I hope that helps.

    Fizix,

    Thanks a lot for the confirmation. It helps a lot. 

    "Non-hermetic" means that the mirrors on DLP6500FYE DMD is exposed to the air right? And the DLPLCR6500FLQ is hermetic correct? 

    I saw that DLPLCR6500FLQEVM is much more expensive than DLPLCR65EVM. Any other differences worth mentioning between the two, besides hermetic and illumination range? Same question for DLPLCRC910EVM and DLPLCRC900EVM. 

    I found the following links to the Xilinx VC-707 EVM, but none of them are currently available. Did I search wrong direction?

    EK-V7-VC707-CES-G AMD | Development Boards, Kits, Programmers | DigiKey

    EK-V7-VC707-G Xilinx | Mouser

    EK-V7-VC707-G-J - Amd Xilinx - EVALUATION KIT, VIRTEX-7 FPGA, JPN MKT (newark.com)

    AMD Virtex 7 FPGA VC707 Evaluation Kit (xilinx.com)

    Thanks,

    Hello again Charles,

    Non-hermetic means that the encapsulant that holds the glass and seals the package is not 100% impermeable.  It is not directly exposed to air.

    The DLPC900 controller is an ASIC chip that is primarily a video controller, whereas the DLPC910 is a Virtex 5 LX30 FPGA and is a binary pattern controller.  The capabilities are quite different.

    The DLPC900 understands RGB input video, and the DLPC910 only understands binary pattern input but can display binary patterns much faster than the DLPC900.

    As an analogy think of a regular computer processor versus an ARM processor.  For certain types of tasks an ARM processor can be much faster.

    Does that help?

    Charles,

    Regarding the Xilinx VC707 EVM your search is correct.  You may want to try looking at surplus suppliers or even sites like ebay.  Not long ago I saw some on a surplus site, but do not recall the name.

    Fizix,

    Thank you so much for your reply. It truly helps a lot. 

    So if am not using the DMD under the water but in the air, then DLPLCR65EVM should work right?

    One more question: on TI website, DLPC900 has a max binary pattern rate of 16129 Hz, and that of DLPC910 is 14989 Hz. But you said DLPC910 can display binary patterns much faster than the DLPC900. Anything I understand wrongly?

    Thanks,

    Charles,

    Yes, unless it is a very humid environment the DLP6500FYE will work fine.

    That can be a bit misleading.  That is across all supported DMDs.  For the same resolution (i.e. DLP6500 on DLPC900 vs on DLPC910 the ,DLPC910 can put out binary patterns faster.  Similarly for the DLP9000 on the DLPC900 vs the DLP9000X on the DLPC910, the DLPC910 is much faster.

    Fizix,

    Got it. So if I use DLP6500 on DLPC900, what is the max pattern rate for binary and video modes? If I use DLP6500 on DLPC910, what is the max pattern rate for binary mode?

    Thanks,

    C

    Charles,

    The DLP6500FYE data sheet has this information in it.  

    The first page shows:

    For more detailed information please see the details of the data sheet.
