8.0 PCB Layout Considerations
To insure proper signal integrity, the module routing must be taken under careful considerations.
This section outlines PCB layout considerations for the SO-DIMM module.
Each section looks at three separate topologies; one for clocks, one for control/address, and one for
data. The assumed loading for this configuration is:
Table 5. Signal Loading
Signal 32-bit 64-bit
Single-sided Double-sided Single-sided Double-sided
clocks 1 load 1 load 2 loads 2 loads
address/control 1 load 2 loads 2 loads 4 loads
data 1 load 2 loads 1 load 2 loads
