data output of the deserializer block in single-width mode with a 10-bit
deserialization factor. The serial stream (0101111100) is deserialized to a value 10'h17C.
The serial data is assumed to be received LSB to MSB.
Word Aligner
Because the data is serialized before transmission and then deserialized at the
receiver, it loses the word boundary of the upstream transmitter upon deserialization.
The word aligner receives parallel data from the deserializer and restores the word
boundary based on a pre-defined alignment pattern that must be received during link
synchronization.
Serial protocols such as PCIe, XAUI, Gigabit Ethernet, Serial RapidIO, and
SONET/SDH, specify a standard word alignment pattern. For proprietary protocols,
the Stratix IV GX and GT transceiver architecture allows you to select a custom word
alignment pattern specific to your implementation.
In addition to restoring the word boundary, the word aligner also implements the
following features:

Depending on the configured functional mode, the word aligner operates in one of
the following three modes:
