Broadcom has introduced a new chipset that will enable operators and service providers to deliver Gigabit performance over currently installed twisted pair copper cabling. The BCM65200 DSP and BCM65900 analogue front end family of chipsets are a high density G.fast solution, providing a critical step in paving the path to Gigabit-speed services over copper to the home.

The device unlocks the Gigabit-speed potential of operator and service provider's installed copper plant, providing fixed line operators with a path to highly-competitive broadband services over the next several years. Complementing the BCM65200/900 family, Broadcom's end-to-end portfolio for residential home gateways includes the BCM63138 with full support for G.fast and G.vector deployments.  Broadcom is showing its full line of G.vector and G.fast technology at Broadband World Forum in Amsterdam.

The BCM65200 DSP and BCM65900 analog front-end VDSL chipset with on-chip vectoring and integrated G.fast support a new state-of-the-art DSP architecture to deliver unmatched levels of integration.  Incorporating up to 36 lines of VDSL2 or six lines of G.fast, plus high-speed vector interfaces that eliminate the need for external PHY and framing devices, the BCM65200/900 family delivers the most power-efficient system solution for high-density G.vector DSLAMs as well as new G.fast-based fiber-to-the-distribution point (FTTdp) architectures.

With full backward-compatibility to existing VDSL and ADSL technologies, including simultaneous G.Fast and G.vector crosstalk cancellation, the BCM65200/900 family is the only commercially available chipset solution to provide operators a means to selectively deploy G.fast to new customers in the same system as VDSL2, preventing the forklift upgrade required for alternative solutions.
