A phase locked loop with a programmable counter would do...

It could for example also be used (with different parameters) to adapt a Q40/Q60 videao signal to standard SVGA (I still could not find a modern LCD monitor that could properly display the 1024x512 screen of a Q60... Even monitors that claim doing 1:1 pixel conversion cannot dislay this properly). It could also be used with other old computers out of the QL scene, and would provide a wider customer base...
