6.5. PMA Signals

Table 25.  PMA SignalsIn this table, N represents the number of lanes set in the IP parameter editor.
Name Width Direction Clock Domain Description

phy_tx_lanes_stable

N*2 (PAM4 mode)

N (NRZ mode)

Output Asynchronous When asserted, indicates TX datapath is ready to send data.

tx_pll_locked

N*2 (PAM4 mode)

N (NRZ mode)

Output Asynchronous When asserted, indicates the TX PLL has achieved lock status.

phy_ehip_ready

N*2 (PAM4 mode)

N (NRZ mode)

Output Asynchronous When asserted, indicates that the custom PCS has completed internal initialization and ready for transmission.

This signal asserts after tx_pcs_fec_phy_reset_n and tx_pcs_fec_phy_reset_nare deasserted.

tx_serial_data

N

Output TX serial clock TX serial pins.

rx_serial_data

N

Input RX serial clock RX serial pins.
phy_rx_block_lock

N*2 (PAM4 mode)

N (NRZ mode)

Output Asynchronous When asserted, indicates that the 66b block alignment has completed for the lanes.
rx_cdr_lock

N*2 (PAM4 mode)

N (NRZ mode)

Output Asynchronous When asserted, indicates that the recovered clocks are locked to data.
phy_rx_pcs_ready

N*2 (PAM4 mode)

N (NRZ mode)

Output Asynchronous When asserted, indicates that the RX lanes of the corresponding Ethernet channel are fully aligned and ready to receive data.
phy_rx_hi_ber

N*2 (PAM4 mode)

N (NRZ mode)

Output Asynchronous When asserted, indicates that the RX PCS of the corresponding Ethernet channel is in a HI BER state.
