The XP IOB block provides resources to enable high-speed interfaces between the programmable logic (PL) and the system outside the device. The XP IOB resources are designed to accommodate the signaling needs for high-speed memory and chip-to-chip interfaces that are powered between 1.0V and 1.5V, including LVSTL06. The XP IOB provides internal termination, internal reference generation, support for a diverse set of I/O standards, driver emphasis, and receiver equalization. These features allow the XP IOB to integrate with a diverse range of systems.
