EMI/EMC compliant industrial temp dual port gigabit ethernet reference design

This design allows for performance evaluation of two industrial grade DP83867IR Gigabit Ethernet PHYs and Sitara™ host processors with integrated Ethernet MAC and Switch. It was developed to meet industrial requirements for EMI and EMC. The application firmware implements a driver for the PHY, UDP and TCP/IP stack and HTTP web server examples. The host processor is configured to boot the pre-installed firmware from on-board SD-Card. A USB virtual COM port offers optional access to the PHYs registers. A JTAG interface allows for own firmware development.

Features

• EMI- and EMC-compliant design with wide input voltage range (17-60V) using two DP83867IR Gigabit Ethernet PHYs and AM3359 Sitara™ Processor to work in harsh industrial environments
• Exceeds CISPR 11 / EN55011 Class A radiated emission requirement by >4.6dB
• Exceeds IEC61800-3 EMC immunity requirements: 
        +/-6kV ESD CD per IEC 61000-4-2
        +/-4kV EFT per IEC 61000-4-4
        +/-2kV Surge per IEC 61000-4-5
• Sitara™ AM3359 firmware, including UDP and TCP/IP stack and HTTP web server examples, boots from on-board SD-Card allowing easy standalone operation
• Access to DP83867IR registers via USB virtual COM port allows for custom specific PHY configurations, like RGMII Delay Mode
• Hardware support for Start-of-Frame Detect allows implement IEEE1588 PTP
