Abstract A phase-lock-loop circuit (20) of a television deflection apparatus generates a first signal (OH) at the horizontal frequency (fH) and a second signal (032H) at 32 times the horizontal frequency (fH) that are both synchronized to a horizontal sync signal (SH). A frequency divider (45) that is outside the phase-lock-loop circuit (20) generates from the second signal (032H) a third signal (54a) at the horizontal frequency (fH). The frequency divider (45) is synchronized by the first signal (OH) to cause the third signal (54a) to be in a constant phase relationship relative to that of the first signal (H). The third signal (54a) is used by a phase-control-loop (70) to control the phase of the deflection current (iy).
