Quad-Port 10GBASE-T Transceiver with XAUI, 27mm BGA

The BCM84834 is a complete four-port 100BASE-TX, 1000-BASE-T/10GBASE-T solution operating at 100m over CAT6a or CAT7 unshielded twisted pair (UTP) cable. It is based on a highly advanced digital signal processor-based architecture to allow robust operation over UTP wiring. It 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 BCM84834 is optimized to enable switch, controller, and other general 10-Gigabit Ethernet (GbE) connectivity applications. Each port in the BCM84834 connects to the MAC side thru a XFI interface. This quad port enables customers to design high-density Top of the Rack (ToR) switches and server NIC controllers for data center applications.
