New Series of Compact High-Frequency Oscillators from Epson |
|
By Graham K. Rogers
Epson are reporting the development of three new crystal oscillators in the SG-210S*H series with a size of 2.5mm x 2.0mm that produce signals in a range between 80MHz and 170MHz. Epson has developed these smaller crystal oscillators by using its QMEMS technology: Quartz micro electro mechanical systems. The creation of the new products uses a photolithographic QMEMS process, "to thin a limited area within the crystal blank near the excitation source (electrodes) to create an inverted-mesa structure." Executive Vice President and Chief Operating Officer of Epson's Microdevices Operations Division, Masayuki Morizumi, says that "The new series of oscillators will help enable stable, high-capacity, high-speed communication networks. Going forward, Epson will continue to leverage its QMEMS technology to provide customers with powerful, easy-to-use device solutions - and the ease of mind that goes with them." Production of the series is expected to begin in April this year. Specifications are also available in a PDF file on the Epson site.
