60hz clock for Max 7000s?

--- Quote Start ---

Can someone recommend a 60hz clock for Max 7000s?

I was looking to use 555 timer, but I can't get the duration high to match the duration low.

Ideally part would be 5v and through hole.

Have you considered using a higher frequency oscillator and just dividing that down? Depends on how many LE's you have to spare I suppose. For a 1mhz clock you'd need 1000000/60=16666 = 15 bits.

Not ideal but it's available in 5v and through-hole :-)
