Phase noise mitigation in an analog video receiver implemented in an integrated circuit device. A phase correction value that indicates a phase offset between a synthesized sinusoid and a reference sinusoid conveyed in a horizontal retrace region of a composite video signal is periodically generated. A phase error that will accumulate during an interval between horizontal retrace regions of the composite video signal is estimated based, at least in part, on the phase correction value, and the phase of a chroma signal component of the composite video signal is adjusted based on the estimated phase error.
