Portable instrumentation equipment and communications systems (fixed and mobile) frequently require a high stability oscillator but don’t have either the physical space for or power to drive an Oven Controlled Crystal Oscillator (OCXO). IQD‘s latest TCXO was launched at Embedded World 2014,providing a practical alternative designed specifically for such applications.
Housed in an industry standard 7 x 5mm ceramic package, the new IQXT-200 series offers a class leading frequency stability down to ±0.28ppm across a wide frequency range from 10MHz up to 50MHz. Operating over the standard industrial temperature range from -40 to 85 degrees C, users can select variants to operate off a 3.0V, 3.3V or 5.0V power supply with the current drawn being typically less than 5mA. A wide range of outputs can be specified including HCMOS or Clipped Sine Wave.
Versions are also available which allow the use of an external voltage to control the pullability which caters for applications where the output frequency needs to be locked. All devices are RoHS compliant, reflow soldering compatible and supplied on tape & reel.
