3.7 Signal Layout Considerations
The pinout of the LSI53C320 package ensures that each signal requires
the shortest possible trace length. Use active termination for the bus
connections to the LSI53C320. When choosing an active terminator, set
the load capacitance of the terminator as low as possible.
LSI Logic recommends the use of strip line. Strip line allows tighter
connector placement, which reduces the noise effects from both internal
and external sources. On long trace runs, such as those in a backplane
environment, snaking of traces to equalize their length is appropriate.
Place the decoupling capacitors as close as possible to the via attached
to each corresponding voltage plane.
