Table 3–6. Dynamic Reconfiguration Clocking Interface Settings in Channel Reconfiguration Mode
Transmitter core clocking refers to the clock that is used to write the parallel data from
the FPGA fabric into the Transmit Phase Compensation FIFO. You can use one of the
following clocks to write into the Transmit Phase Compensation FIFO:
■
■
Option 1: Share a Single Transmitter Core Clock Between Transmitters

How should the receivers be
clocked?
How should the transmitters be
clocked?
tx_coreclk—you can use a clock of the same frequency as tx_clkout from the
FPGA fabric to provide the write clock to the Transmit Phase Compensation FIFO.
If you use tx_coreclk, it overrides the tx_clkout options in the ALTGX
MegaWizard Plug-In Manager.
tx_clkout—the Quartus II software automatically routes tx_clkout to the
FPGA fabric and back into the Transmit Phase Compensation FIFO.
Enable this option if you want tx_clkout of the first channel (channel 0) of the
transceiver block to provide the write clock to the Transmitter Phase
Compensation FIFOs of the remaining channels in the transceiver block.
This option is typically enabled when all the channels of a transceiver block have
the same functional mode and data rate and are reconfigured to the identical
functional mode and data rate.
