KYOCERA Crystal Device Corporation Key Developments

Kyocera Crystal Device Corporation Develops Temperature Characteristics-Free Etalon Filter

Kyocera Corp. announced that Kyocera Crystal Device Corporation, in charge of development and manufacturing of crystal devices, has succeeded in developing a temperature characteristics-free etalon filter, a crystal device which has applied the atomic diffusion bonding technique for the first time in the industry. An etalon filter is a component which detects deviations in multiple light wavelengths in high-capacity optical communication transmissions systems. For this new product, Kyocera Crystal Device has realized a temperature characteristics-free etalon filter with high-accuracy, high-reliability and smaller size due to its success in developing a crystal device applying the atomic diffusion bonding technique. The product will be available on a sample basis starting January 2013. Main features are product specifications enable freedom from temperature characteristics and industry's first crystal device to apply atomic diffusion bonding technique. An etalon filter is a component which monitors whether oscillation of light wavelength is steadily conducted in the tunable laser module -- an essential device used for high-capacity optical communication transmission systems -- which transforms electric signals to optical signals for oscillation.

KYOCERA Crystal Device Corporation Develops 32kHz at-Cut Crystal Oscillator

Kyocera Corporation announced that KYOCERA Crystal Device Corporation succeeded in developing an AT-cut crystal oscillator (KC2520M) with an output frequency of 32kHz, which has the world's first low current consumption of 80A. A crystal device for use in electric vehicles and smart meters, the mounting area has also been reduced by approximately 40% compared to conventional products (3225-size) available in the market. The KC2520M (32kHz) will be available on a sample basis in September 2012, and will be on display at the company's booth at the CEATEC JAPAN 2012 exhibition to be held from October 2 to October 6, 2012 at Makuhari Messe in Chiba Prefecture, Japan. Achieving the world's first low current consumption AT-cut crystal oscillator with an output frequency of 32kHz In collaboration with an IC manufacturer, it have achieved a low current consumption of 80A for the first time in the world for an AT-cut crystal oscillator with 32kHz despite its small size. This feature is expected to expand the use of the product for electric and hybrid-electric vehicles for which conservation of battery life is essential. Since the KC2520M (32kHz) uses an AT-cut crystal element that is utilized as a standard frequency source for mobile phones and CPUs, it has better temperature characteristics than tuning-fork type crystal elements and can achieve high frequency accuracy. As a result, it can ensure high accuracy also when used for automobiles and smart meters, for which an accurate clock function incorporated into electronic devices is required in a wide temperature range. In addition, due to its structure which integrates a crystal with an IC, it has higher impact resistance than the tuning-fork type. By making full use of the company's small crystal blank processing technology and IC assembly technology which have been cultivated through development of products for mobile phones and PCs, Kyocera Crystal Device has succeeded in commercializing a 2520-size product with a 40% reduced mounting area compared to the 3225-size product which has conventionally been used for AT-cut crystal oscillators with 32kHz.

KYOCERA Crystal Device Corporation Develops New TCXO for Mobile Communications Handsets

Kyocera Corporation and KYOCERA Crystal Device Corporation announced the successful development of its KT1612 temperature-compensated crystal oscillator (TCXO), which achieves an level of low-phase noise characteristics with the world's smallest size (1.6mm x 1.2mm) for an electronic component mounted in mobile communications handsets including smart phones. The new KT1612 will be available on a sample basis starting September 2012. The smallest TCXO- Kyocera has achieved the world's smallest product size of 1.6mm x 1.2mm, reducing surface area by 40% over conventional Kyocera products, due to the crystal element miniaturization technology accumulated over the years by Kyocera Crystal Device, a company with the number one market share of TCXOs used in mobile communication devices. Kyocera has decreased the low-phase noise by 7dBC (26MHz@1kHz offset) over conventional products, achieving an level through Kyocera's unique circuit design. Since phase noise can cause transmission errors, especially in high-speed wireless communications, it is a vital characteristic for measures against noise. This product is expected to contribute to the application of simpler measures against noise in device design by significantly reducing phase noise.
