AVX/Kyocera Clock Oscillators
GENERAL DESCRIPTION continued
CLOCK OSCILLATOR APPLICATIONS
oscillators may be used in the main processing unit, for all
the add-on boards, video graphics adapters, co-processors,
etc., and all the peripheral devices such as printers,
modems and networking equipment. Many different
companies may be involved in the manufacture of all these
individual parts of the system.
in fax machines, cellular phones, pagers, and radio systems.
These oscillators are typically very high precision,
temperature compensated and voltage controlled devices.

sealed into an all-metal welded package to protect it from
humidity. The case is directly grounded to a pin to help
minimize RF radiation and meet FCC’s EMI specifications.
PACKAGING
pin and 8 pin DIP (dual inline packages) and ceramic SMT
packages in which most of the clock oscillators are available.
Leaded oscillators are tube packaged. SMT K50 units are
tape and reel packaged 1000 units per reel. Tube packages
hold 25 units each for the KXO-01 and KXO-HC series,
and 40 units each for the KHO-HC series products.
