SimpliPHY® VSC8201 PCB Design and Layout Guide Single Port 10/100/1000BASE-Tand 1000BASE-X PHY Introduction This purpose of this application note in conjunction with the VSC8201 Datasheet is to provide information to assist in the design and layout of the VSC8201 Gigabit Ethernet Transceiver. Power Supply Organization and Decoupling The VSC8201 requires a 3.3v and a 1.5v power supply source for operation using GMII, MII or TBI MAC interfaces. In RGMII and RTBI modes, an additional 2.5v supply .
