The following 40-100GbE MAC and PHY IP core signals are available in PHY-only IP core variations:
• Clock signals:
• clk_ref (relevant only for IP core variations with the Sync–E support option turned off)
• tx_clk_ref (relevant only for IP core variations with the Sync–E support option turned on)
• rx_clk_ref (relevant only for IP core variations with the Sync–E support option turned on)
• rx_recovered_clk (relevant only for IP core variations with the Sync–E support option turned on)
• clk_rxmac
• clk_txmac
• PCS and PMA reset signals:
• pcs_tx_arst_ST
• pcs_rx_arst_ST
• pma_arst_ST
• Control and status interface signals to access PHY component registers.
• Ethernet link signals tx_serial and rx_serial.
• PHY output status signals tx_lanes_stable and lanes_deskewed.
• Signals to connect to the external transceiver reconfiguration controller (relevant for Arria V GZ and
Stratix V devices only).
• 40GBASE-KR4 microprocessor interface and reconfiguration interface signals.
The remaining 40-100GbE MAC and PHY IP core signals are associated with the MAC and are not
available in PHY-only IP core variations.
