Hello,
I want to sync UC3879 with an external clock pulse. In the application note( U-154) i saw that, the ic locks with the fastest clock pulse. I also saw that, to provide an external clock-pulse, i need to invert the pulse signal which will feed to a p-mos which will chop a 5V rail to create the pulse. Now my questions are:
1) Is that 5V has to be the reference 5V of the IC?
2) If the answer to the above question is NO, then can i use logic gates' (7486) output directly for clock syncing?
3) Does the external clock frequency affects the max duty cycle?
Thanks in advance
