(2) Changing the Internal Oscillator Circuit of Emulation Pod

An oscillator circuit board for 10MHz is mounted on this product. To use the emulation pod at a

frequency other than 10MHz, build the desired oscillator circuit on the included OSC-2 oscillator

circuit board (bare board) and replace the board installed in the emulation pod when shipped from

the factory.

Figure 3.5 shows a view of the OSC-2 oscillator circuit board (bare board) and where connector pins

are located. Figure 3.6 shows the circuitry of the OSC-2 oscillator circuit board (bare board). Use the

number of oscillator circuits recommended by the oscillator manufacturer.
