Technicalnote 4

The second PLL can recover the storage of hori­zontal output stage maintaining a constant duty
cycle till the trailing edge of the output pulse gets
the trailing edge of the flyback pulse. From this
pointon, only the leadingedge of the outputpulse
willbe shifted coveringa totalphaseshiftof:0.30T;
overcomingthisvalue,it will producea notch in the
output pulse (@ f

= 27kHz).
