5. Oscillator Circuit
5.1 Oscillator Circuit Board
The M38C29T-ADF has a built-in oscillator circuit board on which a 4.0MHz oscillator is mounted.
Figure 5.1 shows an external view of the OSC-2 oscillator circuit board (bare board) and where connector pins are located. Figure 5.2
shows the circuitry of the OSC-2 oscillator circuit board (bare board). Use the number of oscillator circuits recommended by the
oscillator manufacturer.
