Generate Internal CLK10 and Drive to the Backplane
In Figures C-5 and C-6, switch S5 uses the alternate configuration to
generate the VXIbus CLK10 signal. Instead of the onboard oscillator, the
VXI-1394 generates from the external CLK SMB connector and drives to
the backplane. You can choose whether to terminate the signal using S1.
Polarity remains irrelevant to these configurations.
