DAISHINKU CORP. (President :Sohei Hasegawa) announces
the development of the DSV211AR, the world’s smallest
Voltage Controlled Crystal Oscillator (VCXO).
Since one-segment
broadcasting had started in 2006, it has been in high
demand and mounted on Mobile communication equipment,
such as mobile phones and PCs, and automobiles. This
equipment has become smaller with a higher expectation
by the industry, as well as the products made with these.
The DSV221S, 2.5*2.0mm VCXO, was developed to
meet these needs on May, 2008. DAISHINKU CORP.
developed the DSV211AR and succeeded in further miniaturization
and upgrading. The oscillator is the world’s
smallest VCXO, its size is 2.0*1.6*0.72(0.8mm max.)
and especially suitable for use in tuner modules for
one-segment broadcasting of mobile phones as well as
other products.
Compared with its conventional 2520 size, the volume
is reduced by 44% (0.0041cc to 0.0023cc), and the area
is also reduced by 36% (5.0mm2 to 3.2mm2). The
downsizing makes high density packaging possible.
As for securing the frequency adjustment range, which
is more difficult in downsizing, adopting newly developed
Oscillating circuit IC and crystal resonator made it
possible to expand more than +/-110*10-6 min. It also
can expand operating temperature range from -40 deg.C
to +85 deg.C (-30 deg.C to +85 deg.C with 2520 size).
The expansion made it possible to use the oscillator
more easily and improved its performance.
The oscillator can operate at +1.8V supply voltage.
The DSV221AR provides a very low current consumption
of up to 1.2mA operating at +1.8V supply voltage. The
oscillator is an environmental responsive product which
is lead-free and RoHS compliant.
