1. General timing numbers based on LVCMOS2.5V, 12 mA. Loading of 0 pF.
2. Using LVDS I/O standard.
3. DDR timing numbers based on SSTL I/O.
4. DDR specifications are characterized but not tested.
5. UI is average bit period.
6. Based on a single primary clock.
7. These timing numbers were generated using ispLEVER design tool. Exact performance may vary with design and tool version. The tool
uses internal parameters that have been characterized but are not tested on every device.
