The grounds are also useful for noise isolation and
impedance control.
PCB RECOMMENDATIONS
General guidelines for the PCB design:
•
•
•
Floor plan, locate MPL SER near the connector to limit
chance of cross talk to high speed serial signals.
Route serial traces together, minimize the number of layer
changes to reduce loading.
Use ground lines as guards to minimize any noise coupling
(guarantees distance).

•
Avoid parallel runs with fast edge, large LVCMOS swings.
Also use a GSGSG pinout in connectors (Board to Board
or ZIF).
DES device - follow similar guidelines.
Bypass the device with MLC surface mount devices and
thinly separated power and ground planes with low
inductance feeds.
High current returns should have a separate path with a
width proportional to the amount of current carried to
minimize any resulting IR effects.
