Crystal Units are made of high stability piezoelectric quartz crystal that function as a mechanical resonator. With the advance of the IC technology, various equipment may be controlled by a single LSI integrated circuit, such as the one-chip microprocessor.
Crystal units can generate clock signals which are essential for ICs and LSIs to operate, achieving high stability, adjustment-free performance and miniaturization. At present, crystal units find a broad range of applications such as communication satellites, mobile communication devices, automotive electronics, TVs, personal computing and home information appliances such as DVD equipment.
