I am currently working on such a board for the PCI bus as well as the
CompactPCI bus. This board is capable of 50 MHz operation with a DDS to
generate the clock for playback or using a clock input for record. We could
likely run the playback from an external clock as well. The total bit rate
is up to 200 Mb/s with the input using from 1 to 8 input bits. The
interface is differential ECL. We could remove the translator chips and run
TTL if needed, but at less than 50 MHz. 

This board was designed to operate in a continuous manner recording or
playing back data from a hard disk array. However the board can be used
separately as a data acquisition board. It has 16 MB of memory on board for
intermediate storage of sample data. It is currently being used as a slave
on the PCI bus, but is capable of being a bus master for continuous
transfers to memory. 

The board is currently a custom design for a Government customer, but we
certainly could adapt it for your application. We are performing the final
debug on the PCI version now. The drivers are written for a real-time
version of Windows NT. 

Please let me know if you are interested.
