You may be able to remember me as the only guy in the crowd of transmission people that worked on Radio and DSP stuff. I plan to latch the data after translation to cleanup any package to package skew from the ECL-TTL translators.
Some options require alot of packaging.
Parallel end terminate bus. National claims that they have it working in the lab in multidrop. I would appreciate any input or thoughts that you would have. You should only do the translation at one point, where the signals enter the board, and then accomplish the remainder of the distribution using CMOS logic. I suggest you get yourself a transmission line simulator to work out the details.
