14-stage ripple-carry binary counter/divider and oscillator

The recommended values for these components to maintain agreement with the typical

oscillation formula are:

Ct  100 pF, up to any practical value,

10 k  Rt  1 M.

12.2 Typical crystal oscillator circuit

In Figure 7, R2 is the power limiting resistor. For starting and maintaining oscillation a

minimum transconductance is necessary.
