SDRAM Clock Topology
SDRAM Clock Routing Guidelines
PCI Topologies
The IXP42X product line and IXC1100 control plane processors’ PCI controller is
designed and provides a PCI-bus interface that is compliant with the PCI Local Bus
Specification, Rev. 2.2. For more information on the PCI Bus interface, see the PCI
Local Bus Specification, Rev. 2.2.
• Clocks must be routed with as much of the trace on inner signal layer as possible.
• Clocks on the inner layer have a 5-mil ground trace surrounding them with vias
• Clock traces must be 5 mil wide with 15 mil spacing to any other signals.
• All the SDM_CLK trace should be equal in length, and Topology 1 is also
stitched to ground at 0.5” intervals.
recommended for two banks of SDRAM implementation.
