and receiver phase compensation FIFO clocks in order to reduce the global, regional,
and periphery clock resource utilization in your design.
The transmitter phase compensation FIFO compensates for the phase difference
between the FPGA fabric clock (phase compensation FIFO write clock) and the
parallel transmitter PCS clock (phase compensation FIFO read clock). The transmitter
phase compensation FIFO write clock forms the FPGA fabric-transmitter interface
clock. The phase compensation FIFO write and read clocks must have exactly the
same frequency, in other words, 0 parts per million (PPM) frequency difference.
Arria II GX and GZ transceivers provide the following two options for selecting the
transmitter phase compensation FIFO write clock:

Quartus II Software-Selected Transmitter Phase Compensation FIFO Write
Clock
If you do not select the tx_coreclk port in the ALTGX MegaWizard
Manager, the Quartus II software automatically selects the transmitter phase
compensation FIFO write clock for each channel in that ALTGX instance. The
Quartus II software selects the FIFO write clock depending on the channel
configuration.
Non-Bonded Channel Configuration
In the non-bonded channel configuration, the transmitter channels may or may not be
identical. Identical transmitter channels are defined as channels that have exactly the
same CMU PLL input reference clock source, have exactly the same CMU PLL
configuration, and have exactly the same transmitter PMA and PCS configuration.
Identical transmitter channels may have different transmitter voltage output
differential (VOD) or pre-emphasis settings.
