Tip!
Ajitter* up to ±200 µs on the LOW-HIGH edges of the Sync signal is permissible. The size of the jitter
affects the parameterisation of the ”time window”.
*) Jitters are phase shifts, i.e. time differences of signal frequencies. These are differences in fixed
times (e.g. the transition time from one signal amplitude to another) of a digital signal. Jitter occurs
mainly with high frequencies and can result in loss of data.
