I'm sure everyone remembers the little 8 pin chip that derived 60 Hz from a
standard NTSC color burst crystal. As I recall there was a companion chip
that would derive 60 Hz from a 5MHz crystal. I have no idea if it is still
available.

The C8051T602 is a micro controller. 8051 is a very common part.
If it did a divide by ten function it was because it was loaded with
software.
