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 50-Ohms.
