  • 1G/2.5G (MGBASE-T)
  • 10M/100M/1G/2.5G (MGBASE-T)
led_link Output 1 Asserted when the link synchronization for 1Gb or 2.5G is successful.
led_disp_err Output 1 Asserted when a 10-bit running disparity error is detected for 1Gb or 2.5G.
led_an Output 1 Asserted when auto-negotiation is completed.
  • 2.5G (MGBASE-T)
  • 1G/2.5G (MGBASE-T)
  • 10M/100M/1G/2.5G (MGBASE-T)
  • 10M/100M/1G/2.5G/5G/10G (USXGMII)
led_panel_link Output 1 When asserted, this signal indicates the following behavior:
Mode Behavior
1000 Base-X without auto-negotiation When asserted, indicates successful link synchronization.
SGMII mode without auto-negotiation When asserted, indicates successful link synchronization.
1000 Base-X with auto-negotiation Clause 37 Auto-negotiation status. The PCS function asserts this signal when auto-negotiation completes.
SGMII mode with MAC mode auto-negotiation Clause 37 Auto-negotiation status. The PCS function asserts this signal when auto-negotiation completes.
This signal is applicable only when SGMII 10M/100M mode is enabled.
  • 2.5G (MGBASE-T)
  • 1G/2.5G (MGBASE-T)
  • 10M/100M/1G/2.5G (MGBASE-T)
  • 10M/100M/1G/2.5G/5G/10G (USXGMII)
rx_block_lock Output 1 Asserted when the link synchronization for 10G of MGBASE-T and all speeds of USXGMII is successful.
  • 10M/100M/1G/2.5G/5G/10G (USXGMII)
