Found MN3001 BBD's!

Hello people!

Looking for some TDA1022, I've found in a local electronic surplus store a couple of MN3001 1024 staged BBD's! Has someone got an idea of what I could do with 'em? As SAD1024, it has two 512 stages, so I think that could be a possible subtitution for this hard-to-find IC. Am I right?

http://www.datasheetarchive.com/MN3001-datasheet.html <= This is the datasheet for the BBD, just scroll down until finding Panasonic made IC.

Thanks in advance for any answer!

I say give them a try. Just remember to account for the funky power supply needed.
Substituting for an SAD1024 should be doable. Might require a bit of work/experimenting however.
All the Best!

Hey! Thanks for answer! ... I was thinking in all job needed to be done on the IC clocks to match the abilities of the SAD and came to think that a solution based on PICs may be suitable. Do you think this is right?

Please elaborate on your PIC idea. Being "digitally challenged"(oldschool+analog=digital confusion :icon_redface: :icon_lol:), I'm really not sure what your getting at. :icon_confused:
Why not just use a PLL + buffer to clock it? 
If you're going to go digital; I say do it all the way...

This probably isn't the answer you're looking for, but those MN3001 could bring someone's Eventide Instant Flanger or Tycobrahe Pedalflanger back to life.  It would be a shame to use them for projects when other BBDs are available.

Hey oldschool!

I thought that the clock problem of MN30xx when tried to be pushed to SAD limits was on the clock side, but from what I deduct of some reading, it's more a BBD problem. I thought on a PIC so I could solve the problem of the clock getting 'not so squared' when driven into high frequencies. Now (if i'm right) i've understood that the problem is in the BBD and not in the clock generator itself. So my idea of a pic based clock wasn't ok.
I've already got two FV-1 IC's but i'm afraid to damage them when soldering, so I never did anything with them. Besides that, I don't understand how different programs are selected, I know that this is done through 3 pins, but I can't find the correct lo/hi combinations.

Notcboy: I'd have no problem in sending the IC's if someone has a broken flanger! I just thought that I could build a good flanger from it, but now I believe that the unique proyect available for building is A/DA flanger.

Thanks for the input!
Sebastian.
