In single-width mode, the byte deserializer receives 8-bit wide data from the 8B/10B
decoder or 10-bit wide data from the word aligner (if the 8B/10B decoder is disabled)
and deserializes it into 16-bit or 20-bit wide data at half the speed.
Figure 1–81
In double-width mode, the byte deserializer receives 16-bit wide data from the
8B/10B decoder or 20-bit wide data from the word aligner (if the 8B/10B decoder is
disabled) and deserializes it into 32-bit or 40-bit wide data at half the speed.

Byte Ordering Block
In single-width modes with the 16-bit or 20-bit FPGA fabric-transceiver interface, the
byte deserializer receives one data byte (8 or 10 bits) and deserializes it into two data
bytes (16 or 20 bits). Depending on when the receiver PCS logic comes out of reset, the
byte ordering at the output of the byte deserializer may or may not match the original
byte ordering of the transmitted data. The byte misalignment resulting from byte
deserialization is unpredictable because it depends on which byte is being received by
the byte deserializer when it comes out of reset.
which the MSByte and LSByte of the two-byte transmitter data appears straddled
across two word boundaries after getting byte deserialized at the receiver.
