User Guide
■ Native Transceiver PHYs—These PHYs provide complete access to the low-level
PCS and PMA hardware, allowing you to customize the transceiver settings to
meet your requirements. Depending on protocol mode selected, built-in rules
validate the options you select.
Figure 1–2 illustrates the Native PHY IP Core for the Stratix V device.
Figure 1–2 shows that the Stratix V Native PHY connects to the separately
instantiated Transceiver Reconfiguration Controller and Transceiver PHY Reset
Controller.
Table 1–1 shows the datapaths available in the Native Transceiver PHYs for
Stratix V, Arria V, Arria V GZ, and Cyclone V devices.

Datapaths Stratix V Arria V Arria V GZ Cyclone V
PMA Direct: This datapath connects the FPGA fabric directly to
the PMA, minimizing latency. You must implement any required
PCS functions in the FPGA fabric.
vvv—
Standard: This datapath provides a complete PCS and PMA for
the TX and RX channels. You can customize the Standard
datapath by enabling or disabling individual modules and
specifying data widths.
vvvv
10G: This is a high performance datapath. It provides a
complete PCS and PMA for the TX and RX channels. You can
customize the 10G datapath by enabling or disabling individual
modules and specifying data widths.
