n represents the number of bits in each word that need to be serialized by the transmitter portion of the PMA or have
been deserialized by the receiver portion of the PMA. n = 8, 10, 16, or 20.
m represents the number of bits in the word that pass between the FPGA logic and the PCS portion of the transceiver.
m = 8, 10, 16, 20, 32, or 40.

right side of the device, which contains up to 20 high-speed 6.375-Gbps
serial transceiver channels. Each Stratix II GX transceiver block contains
four full-duplex channels and supporting logic to transmit and receive
high-speed serial data streams. The transceivers deliver bidirectional
point-to-point data transmissions, with up to 51 Gbps (6.375 Gbps per
channel) of full-duplex data transmission per transceiver block.

within the Stratix II GX device.
Transceivers within each block are independent and have their own set of
dividers. Therefore, each transceiver can operate at different frequencies.
Each block can select from two reference clocks to provide two clock
domains that each transceiver can select from.
