BCM6020 first single-chip VDSL solution offer support unshielded telephone distribution cable through on-chip advanced digital filtering, precoding equalization techniques. BCM6020 offers system vendors unmatched capability provision high-speed data transmission services twisted pair copper wire supporting applications such Internet access, extensions, work-athome, remote-office switched digital video. Rates Mbps supported fully symmetric. BCM6020 also configured support full-speed ADSL G.Lite data rates. BCM6020 been designed digital subscriber line application where low-cost, low-power compact size paramount. especially suited frame-based applications such Ethernet transport bridging over longreach telephone grade wiring. Spectral compatibility assured virtue programmable center frequency baud rate. With small footprint BCM6020 ideal NIC, Card mini-PCI modem designs. Robustness even severe bursty ingress guaranteed through support on-chip off-chip interleaving memory. This feature useful industrial applications where such ingress problem.

BCM6020 also supports UTOPIA Level Level interfaces easily connected industry-standard Asegmentation reassembly engines. This facilitates delivery multiple virtual circuits traffic classes. flexible frame structure enables transport encoded uncoded traffic, embedded operations channel protocol supported. Automatic rate-adaptive software available support symmetric asymmetric links. BCM6020 employs Tomlinson pre-coding programmable equalizer improve immunity device radio frequency interference that occur case where unshielded wiring used distribution plant. equalizer length programmable thereby effectively combating inter-symbol interference over wide range symbol rates. BCM6020 also ideal connections SOHO routers integrated access devices. Supporting multi-megabit symmetric data rates excess HDSL, SDSL G.Lite, represents next step broadband access small businesses.
