VSC8224
Quad Port 10/100/1000BASE-T and 1000BASE-X PHY with RGMII and RTBI MAC Interfaces
GENERAL DESCRIPTION:
The VSC8224 is the industry’s smallest, lowest power quad port Gigabit Ethernet transceiver and is
ideal for multi-port switch and router applications. In 1000BASE-T mode, the VSC8224’s power
consumption is 30% lower than the next best competitor. In RGMII-to-SerDes applications, its best-in-
class power consumption of 145mW per port is more than 40% lower than that of competitors. The
device’s compact 19mm x 19mm BGA package makes it ideal for high-density switch applications.
Vitesse’s mixed signal and DSP architecture yields 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.
