PCB Crystal Reference
----------------------

|___| |________|

There is a finite list of _manufactured_ crystals. This file aims
to document all of the known speeds that crystals were available in.
Feel free to add to the list if you find another speed crystal on
a PCB, but please DON'T GUESS!
Remember that some very high frequencies (typically above 100MHz) are
generated by a frequency multiplying IC from a lower frequency
crystal.
This is intended as a reference of existing parts to prevent incorrect
clock speed measurements with digital frequency counters being used
in drivers. When measuring clocks, remember that most parts have a
tolerance so be sure to reference existing parts only and not just
accept direct readings as 100% true.
MAME doesn't yet support fractions in crystal frequencies. For example,
XTAL_3_579545MHz should actually be 3579545.454545...Hz (39375000/11).
This is no problem though: see above note about tolerance.
(Thanks to Guru for starting this documentation.)
