DIRECT offers a full line Resonators which meet the performance requirements of today's industrial applications. Ours consumer grade products are rated from -20 to +80 °C, and industrial standards offer stable performance with an operating temperature range. The temperature variation and aging characteristics of the automotive grade serve the market well, providing reliable start up and stable oscillation in microprocessor circuits across a wide variety of applications.
It should be noted that automotive and industrial application circuits, especially in critical applications, should be evaluated and characterized by DIRECT for stability. Please contact our piezo engineering group for IC characterization at the beginning of your design process. We highly recommend all companies to pursue the characterization process which will eliminate potential design issues and liability with regard to stability. DIRECT offers two extending frequency range in MHz and kHz.
