3 Summary

In summary, SpaceWire is a very useful interface for any type of space-grade application that can be implemented in a variety of ways. TI makes it easy for customers to address these use cases with their space-grade, radiation tolerant LVDS devices. See Table 3-1 for suitable TI devices.
