10-Gbit Copper PHY IC Features Two Ports

Teranetics unveiled what it claims is the industry’s first dual-port 10GBASE-T PHY IC. The TN2022 second-generation PHY device doubles the port density of switch and network interface cards (NIC) compared to first generation 10GBASE-T PHYs. A small form factor and low power profile allows switch manufacturers to design as many as 48 RJ-45 ports into a single rack unit. Typically, 48 ports is the highest density available for standalone 1-Gbit Ethernet switches in one rack unit. Because the TN2022 supports development of new 10-Gbit products with the same port count, OEMs can now design systems that deliver 10 times more bandwidth. This second generation PHY consumes 6 W per port and nearly halves the power consumption compared to first generation PHYs, even while operating at cable lengths exceeding 100 meters. In addition, the TN2022 features multi-rate capabilities, enabling use with RJ-45 Ethernet connectors and making it backward compatible with existing 1-Gbit and 100-Mbit network gear. The TN2022 dual-port 10GBASE-T PHY transceiver is available in sample quantities. TERANETICS INC., Santa Clara, CA. (408) 653-2200.
