PWM synchronization

25 February 2016 - 08:28 AM

I need two 50Hz signals with 120us idle period when both signals are down. How to ensure that period? Based on other inputs I will extend or shorten DutyCycle, but again, how to achieve that both signal will stay synced and won't overlap their ON parts?

 

My idea is to create one 100Hz PWM and using an external T flip-flop to split even and odd peaks. Can it be done without external circuit?
