GENERAL DESCRIPTION:
The VSC8221 is the smallest, lowest power Gigabit Ethernet over copper PHY available and is ideal for SFP/GBIC and Media Converter applications. It is the only triple speed copper SFP PHY to meet the stringent MSA power consumption requirement of <1W for the entire module. Its integrated switching regulator enables it to be powered by a single 3.3V power supply, reducing board space requirements and system cost. 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.

FEATURES:
► Very Low Power Consumption at < 700mW
► Single 3.3V Power Supply with On-chip Regulator
► Patented, Low EMI Line Driver with Integrated Line Side Termination Resistors
