Dear members,
I have very bad news concerning the BBD modules with 4096 stages. Yesterday
we received the second batch of BBD circuits with 4096 stages. We tested
them immediately (Florian, thank's for the note concerning the problems of
other BBD buyers) and found that they do not contain a 4096 stages BBD but
only 1024 stages ! Obviously the circuits have been relabelled and contain
probably the very much cheaper MN3207 or BL3207 with 1024 stages only. I've
heard about such relabelling for computer chips but was not aware that it
happens for BBD circuits as well.
Anyway - this will cause problems with A-188-1D (4096 stages version). If
you have already ordered you are not affected as we had 100% testet 4096
stages BBDs in stock and still have about 25 of them left. But if these are
used up we cannot deliver A-188-1D unless we find "real" MN3205 or MN3005.
And probably we will have to increase the price for the A-188-1D as I assume
that we will have to pay much more than for the first batch.
If someone wants to order BBD circuits that are offered in the internet
(e.g. at ebay or from far east suppliers) be careful that you will get the
real parts !
Best wishes
Dieter Doepfer
