I
Video signals are shown as illustration only. All horizontal timing signals in the IC are solely related to the start of the H
that is applied to the IC.
All horizontal timing signals are generated with the help of the internal line locked clock (LLC). One line period is always divided
into 440 line locked clock pulses. Time periods depicted in the figure are only valid for line frequencies mentioned.
