Benta:
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!
OM222O:
How about using a programmable PLL? They are available in quite a large frequency range.
