Mike, Q-Cap made those devices and they worked very well. They also made bus strips and custom devices. It's been awhile. I have'nt followed this thread very closely but now days, as speed increases, there is a trend to use multiple low-ESR caps (ie: 10 0.01uf caps to make 1 0.1uf). There was a good discussion of this in the comp.arch.fpga news group. - Tom At 09:09 AM 1/18/99 -0000, Michael Rigby-Jones wrote: >> At 08:35 AM 1/17/99 -0500, ryan pogge wrote: >> >you can buy sockets for your chips that have decoupling caps built in. >> >> Those are not nearly as nice as they look at first glance.
