Scope
This Standard specifies the physical interconnection media and data communication protocols to enable the reliable sending of data at high­speed (between 2 Mb/s and 400 Mb/s) from one unit to another. SpaceWire links are full­duplex, point­to­point, serial data communication links.
The scope of this Standard is the physical connectors and cables, electrical properties, and logical protocols that comprise the SpaceWire data link. SpaceWire provides a means of sending packets of information from a source node to a specified destination node. SpaceWire does not specify the contents of the packets of information.
This Standard covers the following protocol levels:
• Physical level: Defines connectors, cables, cable assemblies and printed circuit board tracks.
• Signal level: Defines signal encoding, voltage levels, noise margins, and data signalling rates.
• Character level: Defines the data and control characters used to manage the flow of data across a link.
• Exchange level: Defines the protocol for link initialization, flow control, link error detection and link error recovery.
• Packet level: Defines how data for transmission over a SpaceWire link is split up into packets.
• Network level: Defines the structure of a SpaceWire network and the way in which packets are transferred from a source node to a destination node across a network. It also defines how link errors and network level errors are handled.
This Standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.
