DAISHINKU develops the DSO221SW crystal oscillator, achieving narrower tolerances over wider temperature ranges

DAISHINKU CORP.(President: Sohei Hasegawa) announces development of the DSO221SW, a small-size crystal oscillator
(SPXO)(size: 2520) that achieves narrower tolerances over wider temperature ranges.
In recent years, electronic devices continue to reduce in size while achieving ever higher performance and functionality. Demand
continues growing for electronic components making up these devices to meet this trend.
In the field of short-distance wireless communications, especially, improved communication speeds and high precision are
top priorities. Meanwhile, enhanced multifunctionality has accompanied increased device density as well as additional heat
from the   ICs, which raises concern about higher temperatures in product sets. For these reasons, it is imperative
that electronic components ensure high precision over broader operational temperature ranges.
The DSO221SW crystal oscillator has been developed to meet these challenges.This product achieves narrow tolerances over
wider temperature ranges(e.g., +/-10*10^-6 at -20 to +70deg.C, and +/-30*10^-6 at -40 to +105deg.C). Its volume (2.5*2.0*0.8 mm
externally) is approximately 45% smaller than that of the conventional DSO321 series (3.2*2.5*0.9 mm). Thus, the DSO221SW
meets the needs ofsmaller size and enhanced multifunctionality in short-distance wireless modules.
Narrower tolerances have been achieved compared with conventional SPXOs by taking advantage of the frequency control
technology used in temperature-compensated crystal oscillators (TCXOs).
With operation guaranteed at temperatures up to +105deg.C, the DSO221SW is well suited for car electronics applications.
Featuring a broad frequency range (3to54 MHz), the DSO221SW is operable from low (+1.8V) to high (+3.3V) voltages.
The DSO221SW also boasts excellent environmental performance that meets the lead-free requirements and RoHS Directive
in Europe.
