Frequency chips

Our frequency chip offer relies on two major manufacturers: Seiko Epson and Seiko Instruments, which own 60 to 70% of in casing or cylindrical 32,768KHz quartz market. Seiko Epson is the world number 1 with 16% Quartz and Oscillators market shares, with smaller casing,the largest offer and smallest consumption on the market for SPXO. Seiko Epson and Seiko instruments offer the largest range in terms of RTC casing, consumption and functions. Seiko Epson is the only manufacturer in the world of frequency chips which controls its production line from Wafer Fab Quartz and IC’s to tests and encapsulation. Seiko Epson, with itsQMems lithographic photo technology produces the smallest casing on the MHz Quartz market.
