Decoupling Recommendations
Figure 79. Suggested Component Placement
In addition to the isolation region mentioned in “Power
Connections” on page 229, adequate decoupling capacitance is
required between the two system power planes and the ground
plane to minimize ringing and to provide a low-impedance path
for return currents. Suggested decoupling capacitor placement
is shown in Figure 79.
Surface mounted capacitors should be used under the
processor’s ZIF socket to minimize resistance and inductance in
the lead lengths while maintaining minimal height. For
information and recommendations about the specific value,
quantity, and location of the capacitors, see the AMD-K6
Processor Power Supply Design Application Note, order# 21103.
