多功能三通道200 Mb/s抗辐照SpaceWire节点控制器设计与实现

Design and Implementation of Multi-functional,Tri-channel 200Mb/s Radiation Harden SpaceWire Node Controller

针对航天器应用,提出了一种多功能、三通道高可靠速率可达200 Mb/s的SpaceWire节点控制器设计实现方案.通过DS高速时钟恢复技术、单粒子翻转容错设计、芯片多时钟域划分实现了高可靠、多功能的抗辐照SpaceWire节点控制器.

For Spacecraft application,A multi-functional,tri-channel 200 Mb/s radiation harden SpaceWire node controller is introduced in this paper.This algorithm proposed use three techmique to improve product performance,which is DS high-speed clock recovery technique,SEU-tolerant design method.This controller meets the requirement of spacecraft application and affords a good reference for aerospace reliability.
