what about cheap crystals for microcontrollers.. I think the Arduino,
for instance, uses a crystal (and the oscillator electronics are inside
the Atmel part)
The Arduino Ethernet I have sitting in front of me has a fairly large
can labeled T25.000 that looks an awful lot like a crystal, rather than
an oscillator.
The published Arduino Uno schematic shows a crystal.
