| + | ==== Voltage In ==== | ||
| + | Any voltage between 0-5V at the VIN pin can control the frequency. Without any input resistor the potentiometer wont have any effect on the frequency. But with an input resistor and depending on its value both the potentiometer and the input voltage will define the frequency. | ||

| + | ==== Sync ==== | ||
| + | |||
| + | For the Sync input one can use any 0-5V source, preferable a pulsed one. A diode in forward-biased direction is needed at the input. An additional resistor can decrease effect of the syncing signal.\\ | ||
