VSC8558
Octal Port 10/100/1000BASE-T and 1000BASE-X PHY
G E N E R A L D E S C R I P T I O N :
The VSC8558 is a low power octal Gigabit
Ethernet transceiver ideal for mulit-port
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.
switch and router applications. 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.
