F.4 ADAPT Sequence
This section provides additional guidance for the ADAPT sequence specified in Section 4.7.2.3. The ADAPT
sequence is defined as an 8b10b encoded pattern of MK0, followed by a PRBS9 sequence 511 bits in length,
beginning with 9 b1 bits and ending with a single b0 bit. This is shown in Figure 79.
Figure 79 One ADAPT Sequence before 8b10b Encoding
The line coding is defined in Section 4.5, which also specifies that the LSb of an 8b10b encoded symbol is
transmitted first. The ADAPT sequence before and after 8b10b encoding is shown in Figure 80, based on the
definitions in Section 4.5.

The start and end fragments of the serialized 8b10b encoded ADAPT sequence are shown in Figure 81.
