Dear experts,
In the compact-PCI spec (PICMG 2.0 R3.0) on page 25, they describe the next
signals:
PRST#,DEG#,FAL#,INTP and INTS, all these signals are TTL signals described
on page 25.
But my question is, when it shall be a TTL signal level then I need to use a
5V level signal, wright?
Or can i take also a 3.3V level signal for those signals????
In my design I use a V(I/O) of 3.3V.
My next question is: How to use the GA(4..0) signals on my system board, how
do I need to connect this??
Best regards,
Nico
