Yole Développement is pleased to publish the reverse costing report of the new generation of MEMS oscillator supplied by Discera. The DSC8002 is a programmable CMOS oscillator incorporating a Silicon MEMS resonator. Thanks to the TSV technology of Silex Microsystems (TSI™, Through Silicon Insulator), this new generation of Discera wafer-level packaged MEMS resonator achieves an area of ~0.3mm². The DSC8002 is available in industry standard packages (2.5 x 2.0 x 0.85 mm, 3.2 x 2.5 x 0.85 mm, 5.0 x 3.2 x 0.85 mm and 7.0 x 5.0 x 0.85 mm) and can replace standard crystal oscillators. This report provides complete teardown of the MEMS oscillator with:
