ADSL2+ chipset for IP-based central-office equipment

13 July 2005 Telecoms, Datacoms, Wireless, IoT

STMicroelectronics has available samples and reference boards of its CopperWing12e chipset for ADSL2+ Central Office equipment. The new 12-port second-generation solution embeds an enhanced ATM/IP (asynchronous transfer mode/Internet Protocol) cell processor with fast connection speeds and high realtime processing capability. With the additional GMII (Gigabit Media Independent Interface) Ethernet interface, ST claims its latest ADSL chipset is setting new standards for central-office devices that transfer signals from multiple customer connections onto a high-speed backbone line.

The CopperWing12e chipset integrates all ADSL functions from the ATM/IP interface to the line in three devices. The STLC60243 dual-channel ADSL Line Driver handles high-speed signals over a large bandwidth with a very low distortion rate. The STLC60454 four-channel ADSL Analog Front End connects the line driver and hybrid balance circuit with the digital modem chip. The key component of the chipset is the discrete multitone data-pump with 12 independent transceivers, offering bit rates up to over 26 Mbps downstream and 3 Mbps upstream.

The CopperWing 12e chipset supports multiple ADSL standards, including legacy protocols, as well as a number of advanced features, such as the Reach Extended ADSL (G.992.3 Annex L), lengthening the subscriber loop beyond 6,6 km, and the Enhanced Upstream (G.992.3 Annex M) with bit rates up to 3 Mbps.

ST offering includes a reference design, implementing a 48-channel IP DSLAM line card and featuring four STLC61266 devices connected in a daisy-chain configuration by means of two Gigabit Ethernet interfaces. In addition, a full-feature SW package as well as a dedicated software development kit is provided, enabling customers to implement and customise proprietary features in the PerFlow processor.
