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.”
