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.
The VSC8244 is the industry’s smallest, lowest power quad port Gigabit Ethernet transceiver for low-cost
RGMII and RTBI switch and router applications. In 1000BASE-T mode, the VSC8244’s power consumption
is 30% lower than the next best competitor. The device’s compact 19mm x 19mm BGA package is ideal for
