AC ELECTRICAL CHARACTERISTICS
(VDDA = VDD = VDDQ = 2.4V to 3.6V, and VDDQ = 1.4V to 1.6V for MAX9451, TA = -40°C to +85°C. |VID| = 200mV, VCOM = |VID / 2| to
2.4 - |VID / 2|. Typical values at VDDA = VDD = VDDQ = 3.3V and VDDQ = 1.5V for MAX9451, TA = +25°C. CL = 10pF, clock output =
155.5MHz and clock input = 19.44MHz, unless otherwise noted.) (Note 1)
