The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 3:
ESD testing conforms to MIL-STD-883, Method 3015.

Note 4:
The specified limits represent the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guard banding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under “worst case” conditions.

三星刚出的旗舰新机Galaxy S III固然不错，但是高昂的价格不是每个人都能承受的起。昨天我们报道了一部山寨版的i9300，而现在该机价格和具体配置已经全部出炉。 这款山寨的Galaxy S III名叫HDC Galaxy S3，其外形甚至UI界面都与原型机异常相似。该机的三围为138×70×9.2mm，配备了一块4.7寸触摸屏，分辨率只有800×480像素。

从全球来看，智能电视在设备互联接口、内容服务接口、应用程序开发接口、系统安全可信技术等方面的标准尚未统一，厂商采用不同的操作系统和内容接口，各自的应用互不兼容，对产业整体发展造成障碍，在应用丰富度上也很欠缺。近日国内一些家电厂商主办智能电视开发论坛，力图吸引更多的开发者参与进来，从这一点来看，目前还是家电厂商较为主动地在推动智能电视标准化以及各类应用的开发。 TV OS成产业角逐焦点 ...[详细]
