High-density (HD) I/O banks are SelectIO resources designed to support I/O standards with voltages ranging from 1.8V to 3.3V. HDIOs support single-ended and pseudo-differential I/O bidirectional signaling operating at data rates of up to 250 Mb/s (DDR). Limited support for true differential inputs (with external termination) is also available to support LVDS and LVPECL clock inputs. HD banks contain interface logic (HD IOL) that includes registers, a DPLL, and static delay lines to support asynchronous, system synchronous, and clock-based source synchronous interfaces.
