10GBASE-T TRANSCEIVER

The BCM8481 is a complete 10/100/1000/10GBASE-T solution operating at 100m over CAT6a or CAT7 unshielded twisted pair (UTP) cable. It is based on highly advanced digital signal processor-based architecture to allow robust operation over UTP wiring. It 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.
