That seems to be an interesting development, and it's featured on the
frontpage of their website now, but the links all still go to the 'old'
series of boards they make. You can find it in their webshop, but the
price is quite similar to the Xilinx S3ADSP board which also features
1Gb/s ethernet, VGA and a few other goodies.

I'm interested if they'll offer any high-speed (>100Mb/s) ADCs to go on
those connectors, and Gb/s ethernet would be nice too.

Regards, Paul Boven.

As of right now, the s3e-1600 version of the board is listed as
'Shipping immediately'

The trenz boards only offers 55 IO pins for the large FPGA if I read it
right. And they're German so shipping might be rather
expensive to US. The Digilent board has the same 100 pin IO limit as the
original S3E boards, which I
have 3 of. I don't know if the 1600 S3E board has the same huge signal
stubs on the FX2 connector as the
original S3E starter board but those stubs make higher speeds difficult.

What I would like is at least 200 IO signals that can run at over 150Mhz, so
fairly decent & direct signalling. I don't really
want all of the extras, I'll put those on the daughter cards. Also at least
5A power supply.

Any other possibilities ?

hi

S3ADSP board from trenz may actually fit your requirements
those modules are not yet in their online shop, but you can
see high res photos of the modules in Antti-Brain august 2008 issue
first units are actually sold, and the modules should be very soon
be available for general buy also, the main goal for that board was
low cost lots of resources, thats also the reason for low cost
connectors being used - 1.27mm headers not the hirose as other
modules from trenz

a baseboard will also be available with breakout of the module
to 4 x 2x20 100mil headers

I suppose I should have looked again before posting.
It was some months ago that I bought the S3E500 board.

That should be big enough for good sized designs.

if you want a module with 200 high speed IOs this means the module
shoud have connectors with total amount of pins about 400 (for power
and gnd)

that kind of connectors exist, but i bet you have hard time find such
a module
for low price
