They are in 28nm which is blazingly fast but I'm not sure if the i/o
would keep up
I'm after the fastest possible pulses to drive an electro-optic
modulator, with
a goal of making light pulses in the 10-100 ps range.
We are using the SERDES blocks of an Altera part to make fast LVDS
edges, but
the edges are quantized to the SERDES PLL clock, currently 1 GHz. The
fastest
stuff that I've seen coming out of an FPGA is around 60 ps rise/fall,
low level
LVDS. Delay temperature coefficients are terrible in FPGAs, so even if
you can
make fast edges, they drift all over the place.
This is interesting, if expensive.

schönes Wochenende, Gerhard
discrete circuits. Do any of the most recent fpga's meet your needs?A these speeds you are mostly talking about integrated versus
