Hi,
I'm trying to design a 3U backplane for ECB, but i'm wondering, do I need
active termination?
I've found an example in the S100 backplane, with the LM2450 and this is
low terminated 2.7V.
I also found an example of a VME active termination using UC563 32 lines
VME bias generator, the voltage used is 2.94V.
It's only 3x DIL8 and a lot of resistor networks.
Each chip takes care of 32 lines and 3 chips are needed at every side
(beginning and end)
Anyone got ideas about that ? The backplane will be 43.5cm (17.1")
Regards,
Frank
