Using the external clock input

ARM DUI 0114A
A 50-ohm mini-coax connector, SK5, is provided to allow an external clock source to
drive core clock, FCLK, of the ARM710T. A 47-ohm resistor, R20, provides an
approximate 50-ohm termination. The EXT link of LK5 should be fitted before an
external clock source is connected to SK5. Figure 3-3 shows the position of SK5.
