As soon as Sync_x is high and 1 rising edge of Clock_x occurs, the pixels are brought
to the analog outputs. This is again the simulation result of a comparable sensor to
show the principle.
Please note there is a time difference between the clock edge and the moment the data
is seen at the output. As this time difference is very difficult to predict in advance, it
is advisable to have the ADC sampling clock flexible to set an optimal Adc sampling
point. The time differences can easily vary between 5 – 15nsec and have to be tested
on the real devices.
4.2.2 Reduced Row Overhead Time timing
The row overhead time is the time between the selection of lines that one has to wait
to get the data stable at the column amplifiers.
This row overhead time is a loss in time, which should be reduced as much as
possible.
