September 17, 2013 Nihon Dempa Kogyo Co., Ltd. President: Hiroshi Takeuchi New product developed； OCXO with improved frequency temperature characteristics of 10 ppb (SMD type; 14 × 9 mm) Nihon Dempa Kogyo Co., Ltd. (NDK) has developed a new SMD-type oven-controlled crystal oscillator (OCXO) with frequency temperature characteristics of up to ±10 × 10-9 (model: Twin-OCXO™ NH14M09TA; 14.3 × 9.4 × 6.5 mm). This represents an improvement on NDK's previous product (up to ±20 × 10-9) of the same size. This OCXO is intended for use in small base stations for mobile communications (e.g., microcells or picocells) installed in urban areas and elsewhere to accommodate increasing communication traffic. The RF sections of small base stations require compact OCXOs that provide a highly stable reference frequency comparable to those used in macrocell stations. To meet these needs, NDK has used its proprietary twin crystal technology and temperature control technology with digital signal processing, and additionally adopted hermetic sealing package for excellent environmental-proof performance. The results produce the required compactness and performance improvement simultaneously. The Twin-OCXO™ NH14M09TA covers the frequency range from 5 to 40 MHz, and is available with 12 standard frequency levels (10, 12.8, 13, 16.384, 19.2, 20, 25, 26, 30.72, 38.4, 38.88 and 40 MHz) so that customers can promptly test samples. Engineering sample delivery is scheduled for this month, and the start of mass production is scheduled for October. NDK also provides another crystal oscillator based on twin crystal oscillator technology (Twin-DCXO™ NT14M09TA; 14.3 × 9.4 × 6.5 mm; frequency temperature characteristics: up to ±50 × 10-9). The product has the characteristics of low power consumption and quick start-up. The Twin-OCXO™ and Twin-DCXO™ models are tailored to meet various requirements including those relating to frequency temperature characteristics, power consumption and the start-up time of communication infrastructure, base stations for mobile communications, and optical communications devices, whose components undergo constant downsizing. Note1; NDK will showcase the new product at the CEATEC Japan 2013 event, held from October 1 to 5, at Makuhari Messe (Chiba city). (NDK booth: No. 2A60, Hall 2). Note2; Twin-OCXO™ and Twin-DCXO™ are NDK’s trademarks of the OCXO and the DCXO using the company’s proprietary twin crystal technology.
