Datasheet
4 Timing diagrams
4.1 Sequencer control signals
There are 3 control signals that operate the image sensor:
• SYS_CLOCK
• Y_CLOCK
• Y_START
These control signals should be generated by the external system with following time
constraints to SYS_CLOCK (rising edge = active edge):
T_SETUP >7.5 ns.
T_HOLD > 7.5 ns.
It is important that these signals are free of any glitches.
Figure 20: Relative timing of the 3 sequencer control signals
Figure 21 shows the recommended schematic for generating the control signals and to
avoid any timing problems.
