The device's compact BGA package is optimal for high-density switch applications. Vitesse's mixed signal and DSP architecture yield robust performance, supporting both. full and half duplex 10BASE-T, 100BASE-TX, and 1000BASE-T over >140m of Category 5, unshielded twisted pair (UTP) cable, with industry leading tolerance to NEXT, FEXT, Echo, and system noise. The VSC8558's dual 1.25 Gbps SerDes per port allows for simulatneous support of SGMII/1000BASE-X MACs to SerDes or copper media on a per port basis.
