For 1 Million samples per second you might be able to use one of our PCI FPGA
I/O cards. Its just a target device so 1 million 32 bit readings per second is
about the top speed but it could do the clock generation, syncronous sampling
(say 5 channels x 6 bits per word) and have a small (1 K word or so) FIFO to
allow for interrupts etc. I'm willing to donate a card (and make a simple FPGA
config) if you like.
