Selectable I/O Standards in Cyclone II Devices CII51010-1.1 Introduction The proliferation of I/O standards and the need for improved I/O performance have made it critical that low-cost devices have flexible I/O capabilities. Selectable I/O capabilities such as SSTL-18, SSTL-2, and LVDS compatibility allow Cyclone™ II devices to connect to other devices on the same printed circuit board (PCB) that may require different operati...
