BCM84812

Description

The BCM84812 is a complete dual-port 10/100/1000/10GBASE-T solution operating at 100m over CAT6a or CAT7 unshielded twisted pair (UTP) cable. BCM84812 is based on highly advanced digital signal processor-based architecture to allow robust operation over UTP wiring. BCM84812 is a highly integrated solution combining enhanced analog front ends with digital adaptive equalizers, ADCs, phase-locked loops, line drivers, LDPC encoders and decoders, echo cancellers, crosstalk cancellers, and all required support circuitry.

The BCM84812 is optimized to enable switch, controller, and other general 10-Gigabit Ethernet (GbE) connectivity applications. BCM84812 supports two four-lane 3.125 Gbps XAUI interfaces to allow connectivity to 10-GbE MACs. One of the four lanes on each XAUI interface is reserved to support the SGMII interface, which offers lower speed 10/100/1000BASE-T operation. This dual port enables customers to design high-density Top of the Rack (ToR) switches and server NIC controllers for data center applications.
