Note to Table 1–29:
(1) A 1 ns adder is required for each VCCIO voltage step down from 3.0 V. For example, tJPCO= 12 ns if VCCIO of the TDO
I/O bank = 2.5 V, or 13 ns if it equals 1.8 V.
Periphery Performance
This section describes periphery performance, including high-speed I/O and external
memory interface, and OCT calibration block specifications.
High-Speed I/O Specification
