Product Overview

The Intel® Ethernet Network Connection I347-AT4 quad, single-chip device contains four independent gigabit Ethernet (GbE) transceivers on a single monolithic integrated circuit (IC) that supports serial gigabit media independent interface (SGMII) on the media access control (MAC) interface in an SGMII-to-copper application. The Intel Ethernet Network Connection I347-AT4 can also operate in dual-port mode. When set by the MAC, the Intel Ethernet Network Connection I347-AT4 uses two independent GbE transceivers (port 0 and port 1) in an SGMII-to-copper application. The Intel Ethernet Network Connection I347-AT4 consumes less than 500 milliwatts (mW) per port, thereby reducing overall system cost by eliminating heat sink and reducing air-flow requirements.

Key features include:

  • Two or four ports SGMII-to-copper 
  • Integrated MDI interface termination resistors and capacitors
  • Supports up to four LEDs per port programmable to indicate link, speed, duplex, and activity functions
  •  Automatic MDI/MDIX crossover for all three speeds of operation (10/100/1000BASE-T)
  • Supports IEEE 1149.1 JTAG and 1149.6 AC JTAG
