WebThe SpaceWire specification defines the Physical, Electrical, and Protocol layers of the interface. SpaceWire operates from 2 Mbps to 400 Mbps over a full-duplex, point-to-point serial link, over a distance of 10 meters. SpaceWire uses a Data Strobe (DS) encoding scheme that encodes the transmission clock with the data WebThe receive FIFO indicates that there is space for eight more N-Chars by requesting the link transmitter to send a flow control token (FCT). The FCT is received at the other end of the link (end B) enabling the transmitter at end B to send up to eight more N-Chars. can max volume damage headphones
