A new 65nm chipset that promises a single solution for the design of ADSL/2/2+ and VDSL2 carrier linecards is now available. Lantiq said its VINAX V3 chipset will give network equipment vendors unsurpassed integration, multiple transmission profiles, low power consumption and integration with emerging technology.

Lantiq said the chipset is the first to boast of on-chip integration of a MELT controller for remote line testing by carriers with no external equipment needed, among other features.


It consumes 0.9W per channel, complying with the environmental design goals for broadband architecture, including the EU Code of Conduct on Energy Consumption of Broadband Equipment. It is designed to work with both Class AB and low-power Class H line drivers. It boasts of 16 channels per chipset in a package size of 29mm by 29mm for VDSL2 Profile 17a while an 8ch solution for VDSL2 profile 30a is 30 percent smaller. The VINAX V3 chipset's external bill of materials is 50 percent less, thanks to feature integration, Lantiq said.

The new chipset can drive data rates up to 150Mbit/s/downstream and 100Mbit/s/upstream on a single line, allowing such services as HD IPTV, high-speed Internet access, multi-player gaming networks and VoIP. Home and business users will enjoy faster data speeds thanks to line bonding techniques at chip and linecard levels. The VINAX V3 also supports full system vectoring, which reduces crosstalk in dense cable bundles, and mobile backhaul applications with up to 500Mbit/s symmetrical data rates.

Chip-level enhancements, features integration and software compatibility with Lantiq's VDSL2 chpset means that the VINAX V3 can support all VDSL2 profiles, used for a card deployed as a DSLAM or CO and even as an MDU card running Profile 30a. Higher density cards with up to 72ch further reduce costs.

Hubert Christl, senior vice president and general manager of Lantiq's Access Networks Business Unit, said VINAX V3 "provides breakthrough performance, best-in-class feature set and unsurpassed flexibility for network upgrades and new deployments," making it a "key technology for successful triple-play service delivery in next-generation network deployments."
