with Serial LVDS Outputs
ELECTRICAL CHARACTERISTICS (continued)
(V_AVDD = 1.8V, V_OVDD = 1.8V, V_CVDD = 3.3V, V_GND = 0V, external V_REFIO = 1.24V, C_REFIO = 0.1µF, C_REFP = 10µF, C_REFN = 10µF,
f_CLK = 50MHz (50% duty cycle), V_DT = 0V, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.) (Notes 2, 3)
