Oscillator-clock generator

This self-starting fixed frequency oscillator circuit gives excellent frequency stability. Rl and Cl comprise the frequency determining network while R2 provides the regenerative feedback. Diode Dl enhances the stability by compensating for the difference between Voh and Vsuppiy

In applications where a precision clock generator up to 100 kHz is required, such as in automatic test equipment, Cl may be replaced by a crystal.
