Cyclone IV devices feature OCT to provide I/O impedance matching and termination
capabilities. OCT helps prevent reflections and maintain signal integrity while
minimizing the need for external resistors in high pin-count ball grid array (BGA)
packages. Cyclone IV devices provide I/O driver on-chip impedance matching and
