The Jedec SSTL_18 specification (JESD8-15a) for an SSTL interface for class II operation supersedes any specification in this
document.
The typical value of Vox(ac) is expected to be about 0.5 × NVCC and Vox(ac) is expected to track variation in NVCC. Vox(ac)
indicates the voltage at which the differential output signal must cross. Cload = 25 pF.
