Notes:
These AC parameters values are preliminary and subject to change without notice.
[1] All specifications reflect 100% output drive (disabled slew rate limiting feature).
[2] Specification 1 through 5 refer to PHI clock output.
[3] Exceeds characterization (data propagation delay needs to be analyzed).
