The 12.85MHZ changeable pulse width generator circuit: the SN74123 includes two monostable triggers, it uses the single chip SN74123 to form the pulse generator. The frequency range of this circuit is 0.054Hz-12.85MHz, so it has the pulse width range of 60ns-18s. If you connect the R1 and R3 to the Vcc through the adjustable resistors R2 and R4, so you get the variable voltage frequency and pulse width, the frequency will change with the control voltage, the pulse width will reversely change with the voltage. The capacitance value is in the range of 1pF-100uF.
