Dual, 65Msps, 12-Bit, IF/Baseband ADC
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = 3.3V, OV_DD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), C_L ≈ 10pF at digital outputs, V_IN = -0.5dBFS (differen-
tial), DIFFCLK/SECLK = OV_DD, PD = GND, SHREF = GND, DIV2 = GND, DIV4 = GND, G/T = GND, f_CLK = 65MHz, T_A = -40°C to
+85°C, unless otherwise noted. Typical values are at T_A = +25°C.) (Note 1)
