About US


No.1 world market share in crystal oscillator ICs

When we started out, we manufactured ICs that used quartz crystals to accurately move the second hand in quartz watches, and, applying the crystal oscillation technology cultivated through the production of these ICs, we were the first in the world to sell crystal oscillator ICs.
Even today, we have the largest share of the world SPXO market.



We have established our own Quality Assurance System based on our Quality Policy and are committed to quality assurance practices to create extremely reliable and environmentally friendly products.
