Hi.

I have just designed one that uses 2 chips, it is controlled by a PC
(parallel port) and it has a software to display measurements.

It works from 1Hz to 80Mhz, and can be improved.. if you want to give
it a try, write me and I will send you the schematics and the software
to play with it. I have one working in a XESS FPGA card, but it
doesn't need all those hardware, just 2 of them.

Regards,

Sure I like to see it. Which 2 chips does it use?
