2.1.5.2 EtherCAT Interface

The HSEC adapter board provides two EtherCAT interfaces for the SOM module which is going to connect with the High-density connector through the two RJ45 connectors with integrated magnetics. PHY DP83826 is configured as Enhanced mode which supports 10/100Mbps speed. Both the EtherCAT ports use a common MDIO Bus to communicate with the external PHY Transceiver.

Two Single port RJ45 Connectors Mfr Part# 7498010210A from Link-PP are used on the board for Ethernet 10/100 Connectivity. RJ45 Connectors have integrated magnetics and LEDs for indicating 100BASE-T link as well as receive or transmit activity.

Features of the DP83826:

  • TX latency: 40ns, RX latency: 170ns
  • Two selectable pin modes ENHANCED mode, BASIC mode
  • Low power consumption of less than 160 mW
  • Single, 3.3V power supply
  • MAC interfaces: MII, RMII
  • I/O voltages: 1.8V or 3.3V
