XAPP520将符合2.5V和3.3V I/O标准的7系列FPGA高性能I/O Bank进行连接 

The I/Os in Xilinx® 7 series FPGAs are classified as either high range (HR) or high performance (HP) banks. HR I/O banks can be operated from 1.2V to 3.3V, whereas HP I/O banks are optimized for operation between 1.2V and 1.8V. In circumstances that require an HP 1.8V I/O bank to interface with 2.5V or 3.3V logic, a range of options can be deployed. This application note describes methodologies for interfacing 7 series HP I/O banks with 2.5V and 3.3V systems
