DSV211AR VCXO

MSC Vertriebs GmbH has introduced the DSV211AR voltage-controlled crystal oscillator (VCXO) from KDS Daishinku Corp.

With the oscillator's size of 2mm x 1.6mm x 0.72m the DSV211AR is claimed to be the smallest VCXO. Compared with its conventional 2520 size, the volume is reduced by 44 percent, from 0.0041cc to 0.0023cc. Additionally the space was reduced by 36 percent which ranges from 5mm to 3.2mm?. The downsizing makes high density packaging possible.

It is well-suited for tuner modules for one-segment broadcasting of cellphones, PCs and automobiles as well as a various other applications.

For securing the frequency adjustment range and expanding of more than 110x10-6 minutes, the oscillating circuit IC and the crystal resonator can be adopted. The expansion enables to use the oscillator more easily and at improved performance. The DSV221AR provides a very low current consumption of up to 1.2mA operating from 1.6V to 3.6V supply voltage.

KDS Daishinku's VXCO is available with an output frequency range at 27MHz and operates in a -40C to +85C temperature range.

The oscillator is an environmental responsive product which is lead-free and RoHS compliant.
