The GVXO-331K is supplied on tape and reel. 1k or 3k pcs per reel are the standard T&R pack sizes for this product. Partial quantities may be supplied on tape (no reel), or in bulk.

Product Description

If you need a competitively priced voltage controlled oscillator for your latest project, the GVXO-331K can help. The miniature surface mount package helps save board space when compared with conventional 14 DIL-style VCXO packaging, and current consumption of only 9mA maximum can help save power, leaving you free to use more power-thirsty components in the rest of your design.

With voltage control functionality, the GVXO-331K provides up to ±90ppm frequency pullability with 10% linearity throughout the 1.4V ±1.4V range. 

Industrial operating temperature range is optionally available with this component, select this option when completing your quotation or contact our team for more information.
