GENERAL DESCRIPTION:
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 high-density switch applications. Vitesse’s mixed signal and DSP architecture yields robust performance,
