Physical Layer Description
Several terms that are used to describe different entities and combinations
of entities involved in specifying how encoding works. This specification
uses the terms and notation defined in
Table 2–4 .
Transmission Order
Code transmission and reception start with bit ‘a’ of the 10-bit code, as
shown in
Figure 2–8 on page 2–19 . The order of transmission of multiple
characters across multiple lanes is described under “Multi-Lane
Alignment” on page 2–44 .
Table 2–4. Terms and Notation
Term Meaning Notation Example
Byte 8-bit value, prior to 8B/10B
encoding; used to refer to general
data.
Character 10-bit value, the result of the
encoding of a byte; used to refer to
general data.
Code-group A specific 10-bit encoding of a
specific byte. Dx.y or Kx.y D26.5
K28.5
Symbol The symbolic representation of a
specific code-group, placed on a
single lane of an actual
implementation. /x/ /COM/
Sequence A series of symbols that are
transmitted in the given order;
given a shorthand name to refer to
the entire sequence. {x} {SDP}
Ordered set A character that is placed
simultaneously on all lanes of a
multi-lane implementation. ||x|| ||ALN||
Ordered set
sequence A series of ordered sets that are
transmitted in the given order, of
which each element appears
simultaneously on all lanes of a
multi-lane implementation. {|x|} {|TS1|}
