CMOS IMAGE SENSOR
With 8-bit ADC
l All output timing delays are measured with output load 60[pF].
l Output delay include the internal clock path delay 6[ns] and output driving delay that changes in
respect to the output load, the operating environment, and a board design.
l Due to the variable valid time delay of the output, output signals may be latched in the negative
edge of MCLK for the stable data transfer between the image sensor and a host for less than
15MHz operation.
