Subject: [SI-LIST] : Non-standard bus termination (2nd posting)
Has anybody out of there any suggestion about the following problem? (I think it
is quite a common one).
I?ve got a board with a non-standard bus of 34 traces. The bus drives a group of
memories.
The lenght of the bus is necessarily higher than the critical lenght (lcr =
tr/2tpd): a termination could be useful. The problem: there are so many traces
that one has to use too many components (34 resistors and 34 capacitors for AC
parallel termination).
What shall I do?
Are there any special components (array) to terminate this type of bus?
Shall I terminate the bus or not? (In past experience not always a termination
was mandatory)
Thanks for any help.
m.p.
