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 I347-AT4 can also operate in dual-port mode. When set by the MAC, the Intel I347-AT4 uses two independent GbE transceivers (port 0 and port 1) in an SGMII-to-copper application. The Intel I347-AT4 consumes less than 500 milliwatts (mW) per port; thereby, reducing overall system cost by eliminating heat sink and reducing air-flow requirements.
