As shown in
Figure 14 on page 36
, the MAC starts each transmission with a preamble pattern. As
soon as the LXT971A detects the start of preamble, it transmits a Start-of-Stream Delimiter (SSD,
symbols J and K) to the network. It then encodes and transmits the rest of the packet, including the
balance of the preamble, the SFD, packet data, and CRC.
Once the packet ends, the LXT971A transmits the End-of- Stream Delimiter (ESD, symbols T and
R) and then returns to transmitting Idle symbols. 4B/5B coding is shown in
Table 11 on page 40
.
Figure 16
shows normal reception with no errors. When the LXT971A receives invalid symbols
from the line, it asserts RX_ER as shown in
Figure 17
.
