Typical values at +25°C. Minimum and maximum values are measured across the specified temperature range of TMIN =

–40°C to TMAX = +85°C, AVDD = 3.3V, LVDD = 1.8V, clock frequency = 10MSPS to 65MSPS, 50% clock duty cycle, –1dBFS

differential analog input, internal reference mode, ISET resistor = 56.2kΩ, and LVDS buffer current setting = 3.5mA, unless

otherwise noted.Typical values at +25°C.
