code group into an 8-bit data code group (8'hBC) driven on the rx_dataout port. The
rx_ctrldetect signal is asserted high synchronous with 8'hBC on the rx_dataout
port, indicating that it is a control code group. The rest of the codes received are data
code groups /Dx.y/.

Byte Deserializer
Some serial data rates violate the maximum frequency for the FPGA
fabric-to-transceiver interface. In such configurations, the byte deserializer is required
to reduce the FPGA fabric-to-transceiver interface frequency to half while doubling
the parallel data width. This module is optional in configurations that do not exceed
the FPGA fabric-to-transceiver interface clock upper frequency limit.
For example, at a 3.2 Gbps data rate with a deserialization factor of 10, the receiver
PCS datapath runs at 320 MHz. The byte serializer converts the 10-bit parallel
received data at 320 MHz into 20-bit parallel data at 160 MHz before forwarding it to
the FPGA fabric.
In Arria II GX devices, you cannot enable the byte deserializer in double-width mode.
However, in Arria II GZ devices, you can enable both double-width mode and the
byte deserializer to achieve a 32- or 40-bit PCS-FPGA interface.
