2.6.2. EMAC PTP Interface

In the EMAC PTP interface section, there are options to turn on for each EMAC to enable the Precision Time Protocol (PTP) FPGA interface. These options are only applicable when an EMAC is routed to the HPS pins. When an EMAC is routed to the FPGA pins, these signals are automatically included in the emac<n> conduit. When enabled, the following signals are made available:

  • emac<n>_ptp_pps_o,
  • emac<n>_ptp_aux_tx_trig_i,
  • emac<n>_ptp_tstmp_data,
  • emac<n>_ptp_tstmp_en,
  • emac_ptp_ref_clock clock input interface
