• Manufacturer Part Number: CYIL1SM4000AA-GWCES
• Description: 4 Megapixel CMOS Image Sensor
• Manufacturer: Cypress Semiconductor Corp.

From bottom to top: Clock_x, Sync_x and output. Output level before the first pixel is the level of the last pixel on previous line
As soon as Sync_x is high and one 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.
Note the 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 Add sampling point. The

time differences can easily vary between 5 ns and 15 ns and
must be tested on the real devices.
Reduced ROT Timing
The row overhead time is the time between the selection of lines
that you must wait to get the data stable at the column amplifiers.
It is a loss in time, which should be reduced as much as possible.
