3) Using the Oscillator Circuit Bare Board
To use this product at a frequency you like, build a desired oscillator circuit on the included OSC-2 oscillator circuit bare
board. Figure 2.19 shows an external view of the OSC-2 oscillator circuit bare board and the connector pin locations.
Figure 2.20 shows the circuitry of the oscillator circuit bare board OSC-2. Use the circuit constants recommended by the
oscillator manufacturer.
