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 operating and I/O voltages.
With these aspects of implementation easily manipulated using the Altera® Quartus® II software, the Cyclone II device family enables system designers to use low cost FPGAs while keeping pace with increasing design complexity.
This chapter is a guide to understanding the input and output capabilities of the Cyclone II devices, including: ■ ■ ■ ■ ■ www.
