10GBase-T PHY Family Requires Only 2-W for 10-m Distances Over Standard Copper Cabling

Mon, 12/05/2011 - 12:00pm
PHY TN8000PLX Technology, Inc. expanded its TeraPHY 10GBase-T PHY family with three new single-, dual- and quad-port integrated transceivers. The upgraded TN8000 PHY devices require only two watts for 10-meter distances over standard copper cabling, which is a popular networking length. These products automatically determine the length of a cable and only use the necessary power to reach that distance. If long reach is needed, the IC is capable of 10 Gbps operation at distances in excess of 120 m on standard Cat6A cabling. The company’s Enhanced Energy Efficient Ethernet (eEEE) for both 10 Gigabit and Gigabit speeds -- a customization of the IEEE 802.3az standard -- implements special low-power idle modes. Suitable for system designers requiring high-security networks, the company enhanced its Media Access Control Security (MACSec) circuits with second-generation MACSec features that include options for either variable or fixed latency for network protection. MACSec allows the setup of very secure private networks by identifying and preventing threats within and beyond a local area network (LAN). Additional features include RXAUI and enhanced KR interfaces and Wake on LAN support. The new TN8000 devices will also be able to use a 39.0625 MHz crystal, in addition to the 156.25 MHz oscillator.
