The data bus on the DDR SDRAM has a low voltage swing
when actively terminated (terminated topology). The termi-
nated topology supports higher data transfer rates and is
less constrained, but it consumes more power. Many
designs should be able to operate reliably without active
termination (unterminated topology). The design con-
straints are smaller memory subsystems and tight control
on routing. See the application note, AMD Geode™ LX
Processor and CS5535/CS5536 Companion Device Layout
Recommendations (publication ID #32739), for more infor-
mation.
When series termination resistors are used, as specified in
the AMD Geode™ LX Processor and CS5535/CS5536
Companion Device Layout Recommendations, the actual
power provided by the V
processor and the series and parallel termination (see Fig-
ure 7-1). Therefore, it is impossible to specify the power
used by the processor’s memory subsystem with one hun-
dred percent accuracy. A conservative estimate, is that
32.5% of the power is consumed by the processor and
