with Serial LVDS Outputs
ELECTRICAL CHARACTERISTICS (continued)
(AV_DD = 1.8V, OV_DD = 1.8V, CV_DD = 3.3V, GND = 0, external V_REFIO = 1.24V, C_REFIO to GND = 0.1µF, C_REFP to GND = 10µF,
C_REFN to GND = 10µF, f_CLK = 50MHz (50% duty cycle), V_DT = 0, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at
T_A = +25°C.) (Note 1)
