The new system-level vector processor (VP) solution from Broadcom removes crosstalk interference on DSL networks. This removal of crosstalk interference enables higher-speed Internet, IPTV and mobile broadband services. The new BCM65500 solution reduces the cost and power of G.vector for the highest-density systems, and provides an affordable and seamless upgrade path for fixed line operators to maximize the performance of existing residential copper network infrastructures.

The BCM65500 enables single device crosstalk cancellation of up to 96 lines, with the multi-device configurations extensible to cancellation of up to 384 x 384 lines. The new device is compatible with Broadcom's first and second generation G.vector modem chipsets, and no external vector processor memory is required. The BCM65500 lowers bill-of-materials, size and power consumption by integrating all 10G-KR interfaces, whilst also providing direct interface to the line cards.

Broadcom's line card and system-level vectoring technologies add performance consistency across DSL lines by accurately measuring and correcting for crosstalk between subscriber lines located in a common cable binder. The new BCM65500 system-level vector processor enables services with throughput well over 100 Mbps downstream from any port of standard xDSL chassis of up to 384-lines. With the upgrade of a single system fabric board in an already-deployed digital subscriber line access multiplexer (DSLAM), Broadcom's G.vector solution requires a comparatively lower investment to more than double the bandwidth of existing copper lines.

Broadcom's BCM65500 vectoring processor is a turnkey system-level vectoring solution that offers Vector Control Entity (VCE) software to manage the BCM65500 and G.vector DSP chipsets, as well as Broadcom's high-performance, power-efficient 28nm XLP® II control processor. The advanced microarchitecture of the XLP II FC-4400 core provides unmatched computational performance for embedded applications, leveraging the 28nm process for industry-leading power and cost, to scale system densities up to 384 lines in a single PCB design.

"G.vector technology enables global operators to deliver high-bandwidth broadband services quickly, easily and cost-effectively by extending the performance of existing copper infrastructures," said Greg Fischer, Broadcom Vice President and General Manager, Broadband Carrier Access. "Our new system-level vector processor, utilizing Broadcom's field-proven G.vector technology and our unique DSL expertise, offers system OEMs a comprehensive solution to support the continued growth of DSL and FTTN services."
