Typical Operating Characteristics (continued)
(V DD = 3.3V, OV DD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), C REFOUT = 0.1µF, C L ≈ 5pF at digital outputs, V IN = -0.5dBFS
differential input, DCE = high, CLKTYP = high, PD = low, G/T = low, f CLK = 65MHz (50% duty cycle), C REFP = C REFN = 0.1µF to GND, 1µF
in parallel with 10µF between REFP and REFN, C COM = 0.1µF in parallel with 2.2µF to GND, T A = +25°C, unless otherwise noted.)
