August 23, 2013 Nihon Dempa Kogyo Co., Ltd. President: Hiroshi Takeuchi Industry’s lowest-current-consumption crystal clock oscillator developed (2520 and 2016 sizes) Nihon Dempa Kogyo Co., Ltd. has developed two crystal clock oscillator models (NZ2520SJ; 2.5 × 2.0 × 0.9 mm/NZ2016SJ; 2.0 × 1.6 × 0.8 mm) featuring the industry's lowest current consumption (max. 0.7 mA for 1.8 V, unloaded, 40 MHz). Crystal clock oscillators have become indispensable as accurate clock signal sources for the synchronization of multiple high-speed processing digital circuits in computers and various other types of digital information equipment. In addition, voltage/current consumption by today’s personal digital assistants (PDAs) including cell phones, tablet computers, laptops, digital still cameras and digital video cameras, needs to be reduced in order to lighten the battery load. To satisfy these requirements, Nihon Dempa Kogyo has developed a crystal clock oscillator by combining a proprietary crystal technology with an optimal integrated circuit (IC) for lower current consumption, thereby achieving compactness, high precision and the lowest current consumption of any such unit in the industry (65% lower than the company’s present corresponding product). Product sample delivery is currently in the planning stage, and the start of mass production is scheduled for this month.
