Description: Two Transistor Sine Wave Oscillator
This oscillator uses
two transistors and operates the crystal in the fundamental mode. C1 and C2 should be
about 2 700 pF for 1 MHz, 680 pF for 5 MHz, and 330 pF for 10 MHz. 150 pF can be used for
up to 20 MHz. The output is a near perfect sine wave. Try varying C1 and C2 for best
waveform. About 2 to 6 Vpp is available. (Reprinted with permission from Popular
