VDSL Reference Design provides crosstalk cancellation.September 10, 2009 -
Providing crosstalk cancellation to groups of 24 pairs of DSL lines, BCM96438v7 DSM3 Vectorized VDSL Reference Design can scale to groups of 48 pairs or more on same line termination board. Vectoring or far end crosstalk cancellation increases line performance by minimizing interference that originates from subscriber lines located in same cable binder. Combined with multiple line bonding technologies, vectorized VDSL can contribute to accelerating availability of mobile broadband services.

Broadcom Adds Cross-Talk Cancellation Capability to Its VDSL2-Compliant Fiber-to-the-x (FTTx) Line Termination Reference Design
New Broadcom(R) Dynamic Spectrum Management Level 3 (DSM3) Vectoring Reference Design Platform Features Superior Crosstalk Cancellation
PARIS, Sept. 2 /-- Broadband World Forum Europe 2009 -- Broadcom Corporation (NASDAQ:BRCM), a global leader in semiconductors for wired and wireless communications, today announced its VDSL2-compliant Fiber-to-the-x (FTTx) line termination reference design featuring uncompromised chipset-level crosstalk cancellation technology. Vectoring or far end crosstalk (FEXT) cancellation significantly increases line performance by reducing the interference that originates from subscriber lines located in the same cable binder. Broadcom's unique technology accurately estimates and significantly reduces such crosstalk noise by processing feedback information from receivers located at the customer premises.
Broadcom's vectorized VDSL technology will enable service providers to increase capacity (throughput/data rates) on infrastructure equipment, extending the value of such equipment while offering a whole range of new broadband service opportunities in the further exploitation of copper telephone lines. This includes enriching bundled service offerings or even extending the reach of existing service packages (such as HDTV broadcasting, pay-per-view and on-demand entertainment) to many more households.
Combined with multiple line bonding technologies, vectorized VDSL can also significantly contribute to accelerating the availability of mobile broadband services (such as mobile TV, live video sharing, 3D gaming, Family Locator services and navigation) by enabling gigabit data rates over existing copper backhaul infrastructures, while also providing easier access to radio base stations upgraded with 3G HSPA and Long Term Evolution (LTE) in sometimes dense urban environments. These capabilities address the growing demand for mobile data generated by 3G, HSPA and LTE by providing a significant leap forward from the inadequate low speed synchronous backhaul technologies.
"We have been demonstrating this breakthrough technology using our end-to-end solutions since last year. By making it available in the form of a fully verified reference design, we've demonstrated our continued leadership in DSL product execution and our confidence to progress vectoring to standardization within the ITU and mass deployment in carrier networks worldwide," said Greg Fischer, Vice President & General Manager of Broadcom's Carrier Access line of business. "This reference design utilizes existing, commercially available Broadcom products, and when combined with software extensions for vectoring, enables our worldwide customer base to take full advantage of familiar tools to enhance the capabilities of their own products while achieving faster time-to-market."
Vectorized VDSL Technology
The Broadcom vectorized VDSL reference design provides crosstalk cancellation to groups of 24 pairs of DSL lines and easily scales to groups of 48 pairs or more on the same line termination board. Broadcom designed a small footprint and flexible software to manage crosstalk cancellation using existing line card controllers which ultimately helps achieve energy-efficient, space-efficient and materials-efficient green designs for service provider networks.
Broadcom will demonstrate the new BCM96438v7 vectorized VDSL reference design at the Broadband World Forum in Paris next week.
