bstract： This reference design enables a complete soluTIon for powering Xilinx® Virtex®-6 FPGA GTX transceivers and Spartan®-6 FPGA GTP transceivers using Maxim‘s power-supply soluTIons.
This fully tested reference design provides a complete soluTIon for powering Xilinx Virtex-6 field-programmable gate array （FPGA） GTX transceivers （on the Xilinx ML623 board） and Spartan-6 FPGA GTP transceivers （on the Xilinx SP623 board） using Maxim’s power-supply soluTIons. The GTX and GTP transceivers require two distinct power-supply rails each as follows：
Design Description—Virtex-6 FPGA GTX Transceiver
Power RailInput Voltage （V）Output Voltage （V）Current （A）Maxim Solution
MGTAVCC121.02510MAX8686
MGTAVTT121.26MAX8686
Design Description—Spartan-6 FPGA GTP Transceiver
Power RailInput Voltage （V）Output Voltage （V）Current （A）Maxim Solution
MGTAVCC121.210MAX8686
MGTAVTT121.26MAX8686
These reference designs provide the required two power rails using four MAX8686 monolithic synchronous step-down converters. The GTX and GTP transceiver power-supply block diagrams are shown in Figure 1 and Figure 2.
