Development of Small Size Crystal Oscillators for In-Vehicle Driving Safety Applications, DSO211SX and DSO221SX, and General-Purpose Small size Crystal Oscillators, DSO211SXF and DSO221SXF


DAISHINKU CORP. (President: Sohei Hasegawa) has developed small size (2016- and 2520-size) crystal oscillators, DSO211SX, DSO221SX, DSO211SXF, and DSO221SXF, and are ready to ship samples.
The SX series mainly targets the in-vehicle equipment market, and conforms to Autonomous Driving Level II, and in-vehicle component reliability standard AEC-Q100/AEC-Q200. The SXF series will be principally sold in consumer-product, telecommunications, and industrial markets. Both series feature high frequency stability over a wide range of temperatures with optimal combinations of our proprietary crystal design and ICs with a frequency adjustment function. They also incorporate castellation, which enables automated optical inspection (AOI) when solder-mounted on circuit boards designed by customers. The output frequency range is 1.0 MHz to 125 MHz, power voltage range 1.6 to 3.6 V, and operating temperature range −40°C to +125°C, with frequency stability of ±50×10−6. In addition, these crystal oscillators have superior environmental performance including complete elimination of Pb (Pb-free soldering) and are RoHS compliant. With the introduction of new crystal piece forming technology, products with even higher frequency stability, ±25 x 10−6 (at −40°C to +125°C) are under development, which will be completed in October 2019.
With the likelihood that installation of an advanced emergency braking system (AEBS) in new vehicles will become mandatory, the market for autonomous driving including advanced driver-assistance systems (ADAS) is expected to grow. Furthermore, reflecting the demands for miniaturization and performance enhancement in consumer and other electronic equipment markets, the needs for crystal oscillators are expanding in different fields including the IoT market.
The SX and SXF series products respond to various needs of customers in diverse markets.
