(VCC = LVDSVCC = PLLVCC = +3.0V to +3.6V, VCCO = +3.0V to +3.6V, CL = 8pF, PWRDWN = high; SSG = high, open, or low;
DCB = high or low, differential input voltage |VID| = 0.1V to 1.2V, input common-mode voltage VCM = |VID / 2| to 2.4V - |VID / 2|, unless
otherwise noted. Typical values are at VCC = VCCO = LVDSVCC = PLLVCC = +3.3V, |VID| = 0.2V, VCM = +1.25V, TA = +25°C.) (Notes 6, 7, 8)
