BCM8481

Description

The BCM8481 is a complete 10/100/1000/10GBASE-T solution operating at 100m over CAT6a or CAT7 unshielded twisted pair (UTP) cable.BCM8481 is based on highly advanced digital signal processor-based architecture to allow robust operation over UTP wiring. BCM8481 is a highly integrated solution combining an enhanced analog front-end with digital adaptive equalizers, ADCs, phase-locked loops, line drivers, LDPC encoders and decoders, echo cancellers, crosstalk cancellers, and all required support circuitry.

The BCM8481 is optimized to enable switch, controller, and other general 10 Gigabit Ethernet connectivity applications. BCM8481 supports the 4-lane 3.125 Gbps XAUI™ interface to allow connectivity to 10 Gigabit Ethernet MACs. One lane of the 4-lane XAUI interface is reserved to support the SGMII interface to support lower speed 10/100/1000BASET-operation.
