Example 3 assumes channels 0 and 1, driven by CMU0_PLL in a transceiver block, are
identical. Also, channels 2 and 3, driven by CMU1_PLL in the same transceiver block,
are identical. In this case, the Quartus II software automatically drives the write port
of the transmitter phase compensation FIFO in channels 0 and 1 with the
tx_clkout[0] signal. It also drives the write port of the transmitter phase
compensation FIFO in channels 2 and 3 with the tx_clkout[2] signal. Use the
tx_clkout[0] signal to clock the transmitter data and control logic for channels 0
and 1 in the FPGA fabric. Use the tx_clkout[2] signal to clock the transmitter data
and control logic for channels 2 and 3 in the FPGA fabric.
This configuration uses two FPGA global and/or regional clock resources, one for the
tx_clkout[0] signal and the other for the tx_clkout[2] signal.
