GigE Mode
Stratix GX devices in GigE mode can use the 8B/10B encoder/decoder,
rate matcher, synchronizer, and byte serializer/deserializer built-in hard
macros. Refer to the GigE Mode chapter for more information about this
mode. The rate matcher and word aligner each have a dedicated state
machine governing their functions. These state machines are active only
in GigE mode.
