My need is following:
Clock of 50% duty cycle of variable frequency of 50KHz to 200Khz. Frequency is pruportional to input voltage. Step of freq variation is 100Hz. If I can use 74hc4046a VCO to generate this clock. Yes or No? if yes then please suggest any application note from where i can get the idea of component value. If any other cheap solution is available or not.
