摘要： Apparatus includes a single-pin input interface, which is operative to sense a voltage across a capacitor of a Resistor-Capacitor (RC) network in which the capacitor is repetitively charging and discharging so that the voltage oscillates as a function of time. A measurement circuit is coupled to measure time durations in which the capacitor is charging and in which the sensed voltage lies between first and second predefined thresholds. A clock generation circuit is coupled to generate an output clock signal having a frequency, and to adjust the frequency responsively to the measured time durations.
