Abstract
A low-voltage-differential-signaling (LVDS) fault detector includes first and second LVDS lines, and a window comparator provides a first output indicating whether a difference between voltages at the first and second LVDS lines is greater than a threshold voltage, and a second output indicating whether a difference between the voltages at the second and first LVDS lines is greater than the threshold voltage. A charge circuit charges a capacitive node when either the first or second output is at a logic low, and discharges the capacitive node when neither the first nor second output is at a logic low. A Schmitt trigger generates a fault flag if charge on the capacitive node falls to a threshold.
