Another solution could be a 30 kHz crystal oscillator (the crystal is a standard value). A /16 stage (simple) followed by a x3 stage (a little more difficult) gives 5.625 kHz. This can be done 100% digitally with a divider and gating/flipflop. "KC" is really 60s, are you that old? The world uses SI units nowadays, which avoids confusion (as you can see from the first needless threads). |

Right on, Benta. I was going to make some comment about what worked in the past, but didn't think it was worth the comments. You have to go back further. I was well on my way building electronics, with tubes, Hertz, what's that ? ? ? in the 40s. --- Looked at some of the same thoughts you came up with. Hope to get working on it some more this week-end. |
| B J:
Hi Benta again. Your last comment got me thinking. I liked what you said, just didn't think along those same lines. (Can't find 30 KC crystals) So, -- start with 60 KC crystal (several on Digikey) divide by eight and multiply by three quarters and I have 5625. That will be close enough. Looks good and will work on this weekend. TNX to all |

Seriously, the Hertz was introduced in 1960, fully displacing the old "KC". There's no reason to use that old name other than to be obtuse! |

How about using a programmable PLL? They are available in quite a large frequency range. |
