MC285SPD-L0B0 Power Requirements

Sebastien Boulianne

Hi again,

I purchased a MC285SPD-L0B0 em-ccd camera and it didn't come with the power supply. I was expecting the camera to have a pretty straightforward power requirements (ex: 12v PSU). Instead, it look like it requires a bunch of different voltage on a 12 pins connector(see the picture below). Not to sure what to do to safely provide power to the camera. 

I also joined the full camera specifications: 2678.MC285SPD-L0B0_Ver1.3.pdf

    Hi Sebastien,

    Sorry for the reply delay. We've been searching the company for information on the power unit for this imager and the imager itself. Unfortunately, the device has been obsolete for some time and it is no longer supported by any of the business units within TI. There may still be a few individuals within TI US or TI Japan that have knowledge about this but hard to tell where they might be. The few individuals we have found that were associated with this project are no longer with the company. I'll take note of this thread and if we do run across anything I'll post a reply.

    Hi Sebastian,

    We've been poking around and it looks like you've been here https://www.cloudynights.com/topic/696836-diy-camera-power-supply/ and I see some good discussion on the power requirements. Lab supplies with common RTN/GND connections is an option but I do think that power sequencing might be an issue for the CCD/Camera.

    TI Japan was the source of the MC285SPD beginning around 2003 but it could also be ordered through a UK company called Melford Resolution, LTD https://www.melres.co.uk/ It's possible that they were contracted by TIJ to design/build this CCD Camera and Supply. It might be worth using their contact page and ask them.

    Another option might be to continue searching the internet using the numerical PN for the power unit in the MC285SPD spec sheet, the MC number or other keywords. If you can find one surplus that would be ideal.

    We've tried to track down info through TIJ but have been unsuccessful so far.

    Thanks, I sent an email to Melres. Is there any technic available to determine the power sequence?

    Hello Sebastian,

    To determine sequencing I would have to at least have a schematic of either the camera or the power unit and even then if there are programmable ICs (micro-p, PLD, FPGA etc.) in the design, I would also need source code for those devices.

    I see a name on the power unit drawing in the MC285 specification (T. Hashimoto) and there is a T. Hashimoto at TI Japan so I'll email that person on the off chance that he was assoociated with this design 17 years ago. Not sure on the odds but I'll give it a shot.

    Thanks you very much for that. However, the more I dig into it the more I'm starting to realize I just bought a rather expensive paper weight. I guess I will have to cross my fingers.

    Thanks again.

    Hello Sebastian,

    Perhaps but there's still the possibility of hearing back from Japan. Also, I assume you checked with the original source for the imager and asked about the power supply. At some point, you could just begin experimenting by getting the mating connector with wires and hooking up lab supplies. You might be able to get it to work. 

    I'm going to close this thread for now, however if anybody replies, the thread will reopen and we can resume discussion.
