What sort of accuracy does one get with various clocks (not including RC)
for a PIC? For MIDI serial, the specs call for 1% timing accuracy. What sort
of difficulty will there be in getting a clock to this accuracy? Is there
any difference in accuracy (or other specs) between a resonator and a
crystal (or diff. types of crystal? What about higher accuracies? What is
the maximum (practical) achievable accuracy (i.e. in production, not like 1
in a 1000 will get it) for various High speed clocks? What about driving
multiple PICs at reliable high speed, anything good for this (be nice not to
have to redesign the circuit when another PIC (and hence load
resistance\capacitance\inductance) are added?

Thanks,
Tom.
