OBP Detailed Timing Specifications

Figure 4 shows the OBP detailed timing specifications.

The OB period is from the fifth to the twelfth clock cycle after the OB pulse is inputted. The average of the black

signal level is taken for eight input cycles during the OB period and it becomes the clamp level (DC standard).
