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 launching at Embedded World 2014 provides a practical alternative and is 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 1.25MHz up to 200MHz. 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 15mA. A wide range of outputs can be specified including LVTTL, HCMOS, Clipped Sine Wave or Sine Wave into 50Ohms. Versions are also available which allow the use of an external voltage to control the pullabilty 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.
Further details will be available at IQD’s stand 650 in Hall 4 at Embedded World 2014.
