TrendChip Technologies, a provider of xDSL CPE chip, has introduced an ethernet switch chip, TC2205F, designed for broadband access platforms. This switch chip has four automatic energy-saving 10/100M ethernet ports, that meet the IEEE 802.3az industry requirement (Energy Efficient Ethernet) and detect network cable length and unused network ports in order to manage power consumption.
Using these energy-saving technologies, telecom service providers can start deploying green energy-saving broadband network, while users can also save energy and reduce carbon emission without being affected in their broadband internet access, TrendChip said.
TC2205F has four 10/100M ports and one MII/TMII (Turbo MII) MAC interface, which is connected to the main CPU on the platform, and 64-pin QFN packaging.
TC2205F combines a series of automatic energy-saving functions, which conforms to IEEE 802.3az, such as, the low energy consumption mode with automatic entry and exit based on actual network traffic (Low Power Idle), and automatic detection of network cable length and unused ports to reduce unnecessary power consumption.
In addition to energy conservation, TC2205F also offers the QoS, VLAN, and IGMP V1/V2/V3 functions, with full and flexible settings, in order to meet the network settings requirements of telecom service providers when deploying Triple-Play.
Bomin Wang, president of TrendChip, said: “When telecom service providers introduce energy-saving chips to their end-products, not only will this go with enterprises’ global trend of energy conservation and carbon emission reduction, it will also effectively prolong the operational life cycle of end-products, and hence, reducing their operating and maintenance costs in the future.”
