DAISHINKU CORP. (President: Sohei Hasegawa) announces the development of the DSO213AW, the slimmest crystal oscillator
in the world (thickness: 0.53 mm), designed to achieve 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
communication modules especially, there has been growing need for reduction in size and thickness. Meanwhile, improved
communication precision is an important challenge, for accommodating ever-higher communication speeds. 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 DSO213AW crystal oscillator has been developed to address these challenges. This product, the slimmest in the world
(2.0*1.6*0.53 mm externally), is approximately 58% smaller in volume than the conventional DSO221 series (2.5*2.0*0.8 mm),
which achieved 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).
The DSO213AW thus meets the needs of reduced size and thickness, as well as enhanced multifunctionality in short-distance
wireless modules and data cards.
Thickness has been successfully reduced by the new back-grinding technology
(which helped make the IC slimmer), while ensuring ceramic base strength. The product thickness of 0.53 mm has been achieved
by employing molten metal encapsulation to control stress applied to the ceramic base, in lieu of conventional electric welding
encapsulation.
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 +105 deg.C, the DSO213AW is well suited for automotive electronics applications.
Featuring a broad frequency range (3.25 to 60 MHz), the DSO213AW is operable from low (+1.8V) to high(+3.3V) voltages.
The DSO213AW also boasts excellent environmental performance that meets the lead-free requirements and RoHS Directive
in Europe.
