Serial LVDS Outputs
ELECTRICAL CHARACTERISTICS (continued)
(AV_DD = 1.8V, OV_DD = 1.8V, CV_DD = 1.8V, GND = 0, external V_REFIO = 1.24V, INTREF = AV_DD, C_REFIO to GND = 0.1µF,
f_CLK = 40MHz (50% duty cycle), DT = 0, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.) (Note 1)
