Figure 5. Optical Black and Offset Correction Timing
NOTE: To avoid the ADC being clipped on differential negative input signals, an internal offset that equals to 255 ADC LSBs is intentionally added
to the PGA output signal. This offset is only added during optical black pixel interval with a total duration of 2N + 3 pixels, where three
additional pixels are necessary for accommodating internal latency adjustment.
