Product Description

Available with high frequency fundamental mode crystal up to 78MHz, the GVXO-55F is a versatile voltage controlled oscillator providing frequency pullability of ±100ppm minimum, with other options available.

With 5.0V supply voltage, voltage control provides better than 10% linearity over the voltage range +2.5 ±2.0V, and enable/disable tristate functionality is available on pin 2.

Industrial operating temperature range of -40 to +85°C is also available and, combined with a miniature surface mount package, makes this VCXO suitable for a wide range of industrial applications.
