Seeking a longer flex cable

Hi Allen,

TI does not sell a longer flex. You can change it yourself, being mindful of any potential signal integrity issues of course. Take a look at this thread: e2e.ti.com/.../367687

Otherwise, look through our solutions and services page: www.ti.com/.../solutions-services.page to see if any of our design network partners can help. I know you were in contact with Keynote Photonics and Adam Kunzman. Does this kit fit your needs? www.keynotephotonics.com/.../

Thanks,

Hi Paul,

I am looking to extend the flex cable length too. Our optical design is quite packed and we would like to put the DLPC350 board away from the optical path.

I have been browsing through the forum conversations and I have a few questions:

- In your e store you offer a flex cable (image below) called DLP5500FLEX. I would like to know how long it is? and if it messes up with the DMD-dlpc350 board connection?

- My other question concern the "DLP® LightCommander™ Development Kit: Extending the Connection Between the Controller Board and the DMD Board" [http://www.ti.com/lit/an/dlpa028/dlpa028.pdf] report. They mention that the extension can be done with two lengths, 5.2" and 12.2". This last one would be great for us. I wanted to know if we would have any connection issues with this extension (between DMD and dlpc350 board) or if it has been tested by TI and it is one of their solutions?

Thank you in advance,

Sincerely,

Elena

Elena,

Unfortunately neither of things you mention are compatible with the DLPC350. Both are for other DMDs and boards and will have different connections than you require.

My recommendation for you is the same - take a look at of our design partners and see if they can offer anything that fits your needs. The Keynote Photonics kit is a good starting point.

Thanks,
Paul

Hi Paul,

Thank you for this information and I am sorry I didn't realized it.
When you say to look the partners designs, do you mean their felx cables or would I need to purchase another DMD or board?

Thank you again,

Sincerely,
Elena

Elena,

If you look at our design partner's webpages, you might be able to find a flex cable that fits your needs or a better EVM.

Thanks,
Paul

Hi Elena,

For our LC4500 Drive board, we link the C350 with a small DMD board using a flexible cable.  This allows the electronics to be located away from the optics. Although the standard cable is only ~2" long, we also offer an optional 30cm cable.

Hi Keith,

Thank you for the information. Would this flex cable work with TI DLp 4500 DMD and DLPC350 board or do we need to purchase the whole kit from Keynote Photonics? If we need to buy all the components, how much would it be?

Thanks again for your help,

Sincerely,
Elena

Unfortunately, the TI development kit doesn't have the appropriate interface. Please send me an email at k-elliott@kp-corp and I'll be happy to assist you.

Best Regards,
Keith
