Tip!

A jitter* up to

±200

ms on the LOW−HIGH edges of the sync signal is permissible. The extent of the

jitter has an effect on the parameter setting of the "time slot".

* Jitter refers to the phase shiftings and therefore to the periodic changes of signal frequencies. They
are variations of fixed points in time (e. g. the time of the transition from one signal amplitude to
another) of a digital signal. Jitter particularly occurs with high frequencies and can result in data
losses.
