Description

This ethernet brick reference design provides a simplified solution that eliminates the need to have multiple boards for copper or fiber interface. It uses a small form factor, low power 10/100 Mbps ethernet transceiver to reduce board size for a cost optimized and scalable solution with reduced power consumption in high temperature industrial applications. The DP83822 provides all physical layer functions needed to transmit and receive data over both standard twisted-pair cables or connect to an external fiber optic (SC or ST or SFP) transceiver. The design provides option to configure different power supply levels for Analog and IO supply using fixed or programmable LDOs. The brick is interfaced to TM4C129X TIVA™ MCU with internal MAC. The design is tested for radiated emission, ESD and EFT as per IEC61000-4 standard level 4.

Features
  • DP83822 ethernet PHY with fiber (100BASE-FX ) or twisted-pair (copper - 100BASETX and 10BASE-Te) interface  
  • Provision to configure analog and IO supply voltage levels separately based on application
  • Programmable LED support for link and activity
  • Meets EN55011 Class-A radiated emission requirements, and meets IEC61000-4-2 level 4 criterion B
  • D83822 works for temperature of 40oC to 125oC
