SpaceWire features automatic link testing when a node is brought on line - released for operation via software. The transmitter sends NULLs until NULLs are received and then sends FCTs until FCTs are received. The initial frequency is specified [ECSS-E-ST-50-12C] to be 10 MHz. Once the aut...
ECSS-E-50-12A是Pacewire总线的标准，涉及链接、节点、路由器和网络，与电缆无关。ECSS-E-ST-50-12C则是ECSS-E-50-12A升级的最新版本。型号不一样，都差多不。有点质量差别
The initial frequency is specified [ECSS-E-ST-50-12C] to be 10 MHz. Once the auto link test has passed, the hardware can switch to the programmed rate. A local oscillator is used to supply the 10 MHz reference clock for initialization. A programmable PLL is used to support operation ...

The SpaceWire standards are maintained and issued formally as ECSS documents (e.g. ECSS-E-ST-50-12C) and this means that equipment designed by different agencies is interoperable, which has significant benefits.SpaceWire is mainly used between instrument units, however to facilitate a high level ...
夏ECSS将各类文件按标准、手册、技术备忘录三种形式进行划分,分别用ST表示标准,HB表示手册,TM表示技术备忘录,如,原标准ECSS-E-40现在为ECSS-E-ST-40;为避免出现“部分(part)”,ECSS-E-30 part 4现更改为ECSS-E-ST-34,新增加的技术备忘录ECSS-E-TM-10-20表示“产品数据交换”,手册ECSS-E-HB-50为“通信...
ECSS.E一40在新发布文件中被改写为 ECSS—E—ST-40: 2)调整ECSS标准体系以增强一致连贯性: 一 重编项目管理类标准以形成更好的统 一 .如:原文件中ECSS.M.40"技术状态管理" 和ECSS—M.50"信息/文件管理"在新文件中被 合编为ECSS.M.ST-40"技术状态和信息管理" ...
