stages in standby mode.
• Eos_x: end of scan signal: is an output signal, indicating when the end of the
line is reached. Is not generated when doing windowing
• Eos_y: end of scan signal: is an output signal, indicating when the end of the
frame is reached. Is not generated when doing windowing.
All digital signals are buffered and filtered on chip to remove spikes and to achieve
the required on chip driving speed. The applied digital signals should be capable of
driving 20pF input capacitance.
3.8.5 Test signals
Some test signals are required to evaluate the optical performance of the image
sensor. Other test signals allow us to test internal modules in the image sensor and
some test signals will give us information concerning temperature and influence of
the temperature on the black level.
