iSAFT SpaceWire Interface Board

The iSAFT Quad/Octal SpaceWire Interface Board is an advanced PCIe SpaceWire interface, supporting SpW simulation with error injection and built-in recording capabilities. It is suitable for multiple applications in the space sector, including Data Front-Ends, EGSE/SCOEs.

The board is based on TELETEL’s powerful SpaceWire codec, and it is a proven solution in various spacecraft /satellite testbeds in Europe and Japan.

The board is delivered with a practical SDK, and can be complemented with additional software modules allowing to save development / integration time.

Main Features
Full height / Half length PCIe form factor board with multi-Gbps overall throughput
Four / Eight SpW Ports with independently programmable Link speed up to 400Mbps, full compliance to ECCS-E-ST-50-12C
SpW Simulation / Emulation capabilities with built-in packet recording functions
IRIG-B002/006 generator / receiver TTL/RS-422 electrical levels, with down to 8 nano-seconds accuracy / resolution, with IRIG signal regeneration capability in order to cascade multiple boards / systems
Asynchronous transmission & Traffic generation support
Per port / packet triggered transmission conditions (packet to packet delay, transmission on Time-Code / IRIG Timestamp with / without time offset, etc.), Packet & Time-Code transmission on external strobe, etc.
Provision of several trigger in / out signals with multipurpose functionality (start of capture stimulation, generation of events, synchronization with external equipment, etc.)
Electrical level self-test capabilities for all interfaces (SpW / IRIG)
