Basic (PMA Direct) mode
In Basic (PMA Direct) mode, each channel must be clocked by its own tx_clkout. As a
result, the number of global and/or regional clock resources required is significantly
higher. In Basic (PMA Direct) ×N mode, to save on global and/or regional clock
resources, you may use tx_clkout from centrally located channels to clock all the
channels. The coreclkout port is not available in Basic (PMA Direct) ×N mode.
The receiver phase compensation FIFO compensates for the phase difference between
the parallel receiver PCS clock (FIFO write clock) and the FPGA fabric clock (FIFO
read clock). The receiver phase compensation FIFO read clock forms the FPGA
fabric-Receiver interface clock. The FIFO write clock and read clock must have exactly
the same frequency (0 PPM frequency difference).
Stratix IV transceivers provide the following two options for selecting the receiver
phase compensation FIFO read clock:

User-selection is provided to share transceiver datapath interface clocks in order to
reduce the global, regional, and periphery clock resource usage in your design.
