I need to design a 555 clock circuit to output a clock pulse of a specific frequency. The circuit I'm using is this one (from here):
I've used this circuit before and it works fine but the website only shows what resistor value to use for a few predetermined frequencies, which are all far too low for what I need. Is there an equation for working out what value of that resistor I should be using?
After looking at the datasheet, I'm still struggling to find the solution as the circuit in the sheet is different, though the one I'm using is tried and tested by myself recently. I'm also limited on what ICs I can use as I only have whats provided to me which is why I'm using an NE555.
Can anyone help with what would be a could resistor value to output the highest frequency clock possible for that chip?
