Hi!
I had a question regarding a single driver driving two
source terminated lines. I have implemented this
scheme successfully on clock lines but now I want to
use this approach on databus.
The databus is runing at 77Mhz and the driver has rise
time of 1ns. The two traces are of unequal lengthby
approx. 900mil. I know in this scheme it is desirable
to have traces of equal length so that the reflection
from the load end arrives at the source at the same
time and ther is not much coupling into each other.
Is this also important for databus or can I have some
slack?
Thanks in advance
Bob patel
