Development of World’s Smallest and Thinnest* Differential Output Crystal Oscillators (Arkh.3G Series), DS1008JC/DS1008JD/DS1008JJ/DS1008JK


DAISHINKU CORP. (President: Sohei Hasegawa) has developed 1008-size differential output crystal oscillators, DS1008JC/DS1008JD/DS1008JJ/DS1008JK, and will start shipping samples in July.
In response to a rapid increase in communication traffic accompanied by the expansion of mobile networks and emergence of big data in recent years, various efforts have been made in research and development of optical transport devices. Digital coherent technology is one of the key drivers of those efforts. Differential output crystal oscillators have been drawing attention as devices supporting this technology. One of the most important performance factors of such devices is implementation efficiency. Downsizing an individual device is demanded to achieve higher efficiency. However, most differential output crystal oscillators in the market are 7050- and 5032-size. The most compact version is the 2520-size device sold by us. The newly developed 1008-size devices are far smaller and thinner compared to the conventional products, thereby contributing to increased implementation efficiency.
This product has been developed as part of the Arkh.3G series, which was realized by our proprietary technology. We have also completed developing a low-voltage clock crystal oscillator, DS1008JN, which operates on 1.2 V. We will expand the lineup of the Arkh.3G series to create new value for crystal devices.
