For Open Drain CPU Output Signals
(with K7 Processor SELP4_K7# = 0)
For Differential CPU Output Signals (with P4 Processor SELP4_K7#= 1)
The following diagram shows lumped test load configurations
for the differential Host Clock Outputs.
Figure 4
is for the 1.0V
amplitude signalling and
Figure 5
is for the 0.7V amplitude
signalling.
