AlphaPC 164UX Jumper Configuration
CPU Speed Selection (Option 1,2,3, &4)
Figure 3–1 AlphaPC 164UX Configuration Jumpers
3.1 CPU Speed Selection (Option 1,2,3, &4)
The clock synthesizer makes it possible to change the frequency of the microproces-
sor’s clock input without having to change the clock crystal. Simply set the speed
jumpers to adjust the frequency of the microprocessor’s clock. These speed jumpers
are located at J28-1/2 (Option 1), J28-3/4 (Option 2), J28-5/6 (Option 3), and J28-7/8
(Option 4). These four jumpers set speed at power-up as listed in Figure 3–1.
