Hello
I'm trying to input a frequency into the SYNC(1) pin of the L297 ic, the datasheet only mentions sync from other L297 but the idea is to use a 555timer from a complete isolated source!
the schematic attached is only for explaining better, do not comment the optocoupler please, it's tested and it deals perfectly with high frequency!
Has anyone done this before , use a 555 timer connected to SYNC pin ?
thks
