Unlike Ethernet, where the LSB of the parallel data byte is transferred first,
SONET/SDH requires the MSB to be transferred first. To facilitate the MSB-to-LSB
transfer, you must enable the Flip Transmitter input data bits and Flip Receiver
output data bits options in the ALTGX MegaWizard Plug-In Manager.
Depending on whether data bytes are transferred MSB-to-LSB or LSB-to-MSB, you
must select the appropriate word aligner settings in the ALTGX MegaWizard Plug-In
Manager.
Word Aligner in SONET/SDH Mode
The word aligner in SONET/SDH functional mode is configured in manual
alignment mode. You can configure the word aligner to either align to a 16-bit A1A2
pattern or a 32-bit A1A1A2A2 pattern, controlled by the rx_a1a2size input port to the
transceiver.
A low level on the rx_a1a2size port configures the word aligner to align to a 16-bit
A1A2 pattern; a high level configures the word aligner to align to a 32-bit A1A1A2A2
pattern.
In OC-96 configurations, the word aligner is only allowed to align to an A1A1A2A2
pattern, so the input port rx_ala2size is unavailable. Barring this difference, the
OC-96 word alignment operation is similar to that of the OC-12 and OC-48
configurations.
You can also configure the word aligner to flip the word alignment pattern bits
programmed in the ALTGX MegaWizard Plug-In Manager and compare them with
the incoming data for alignment. This feature offers flexibility to the SONET
backplane system for either a MSB-to-LSB or LSB-to-MSB data transfer.
lists word alignment patterns that you must program in the ALTGX MegaWizard
Plug-In Manager based on the bit-transmission order and the word aligner bit-flip
option.

OC-48 and OC-96 Byte Serializer and Deserializer
The OC-48 and OC-96 transceiver datapath includes the byte serializer and
deserializer to allow the PLD interface to run at a lower speed. The OC-12
configuration does not use the byte serializer and deserializer blocks. The byte
serializer and deserializer blocks are explained in
“Byte Deserializer” on page
The OC-48 byte serializer converts 16-bit data words from the FPGA fabric and
translates the 16-bit data words into two 8-bit data bytes at twice the rate. The OC-48
byte deserializer takes in two consecutive 8-bit data bytes and translates them into a
16-bit data word to the FPGA fabric at half the rate.
