PGA00[9:0] is used to set the gain of the Programmable Gain Amplifier (PGA).
Code = 0000000000 is minimum gain (6dB). Code
≥ 1001111111 is maximum gain (36dB).
See the “Programmable Gain Amplifier” (pg. 16) and the “Multiple Gain Mode” (pg. 30) sections for more
information.

OBE[8:0] is used in the Multiple Gain mode to program the gain to be applied to Optical Black pixels on Even
lines during Offset Calibration. OBO[8:0] is used in the Multiple Gain mode to program the gain to be applied
to Optical Black pixels on Odd lines during Offset Calibration. See the “Multiple Gain Mode” section (pg. 30)
for more information.

The Calibration register is used to program various options for the Offset Calibration logic.
OBdel[1:0], sets the number of Fringe pixels which should not be used for Black Level Calibration.
Avg[1:0], sets the number of OB pixels to average, 00=32 pix, 01=64 pix, 10=128 pix, 11=256 pix.
DNS[1:0], sets the Digital Noise Suppression filter width, 00=no filter, 01=narow, 10=med, 11=wide.
Mode, sets Calibration mode. 0=Line mode, 1=Frame mode (not supported at this time).
Hold, used to stop calibration updates. 0=Calibration active. 1=stop, hold current Calibration values.
ManCal, used to manually program the Offset DACs. 0=automatic mode. 1=manual mode.
See the “Black Level Offset Calibration” section (pg. 19) for more information.
