Timing v.1.8
1. Timing numbers are based on default LVCMOS 1.8 I/O buffers. Use timing adjusters provided to calculate timing for other standards.
2. Measured using standard switching circuit, global routing loading of 1, worst case PTSA loading and 1 output switching.
3. Pulse widths and clock widths less than minimum will cause unknown behavior.
4. Standard 16-bit counter using GRP feedback.
5. CAM, FIFO, RAM fMAX specification used shared PT Clk.
