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
The lenght of the bus is necessarily higher than the critical leng=
ht (lcr =3D
tr/2tpd): a termination could be useful. The problem: there are so ma=
ny traces
that one has to use too many components (34 resistors and 34 capacito=
rs 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 te=
was mandatory)

Thanks for any help.
