mode. This curve is the relation between the electrons detected
in the pixel and the output signal. This curve was measured with
light of 600 nm, with an integration time of 138.75 ms (10 MHz
pixel rate), at minimal gain setting 0000. The resulting
voltage/electron curve is independent of these parameters. The
conversion gain is 18 µV/electron for this gain setting.
Note that the upper part of the curve (near saturation) is actually
a logarithmic response, similar to the FUGA1000 sensor.

Reset right Y shift register (low active, 0 = sync)
Clock right Y shift register (shifts on falling edge)
(output) low 1st CLK_YR pulse after last row (low active)
Reset X shift register (low active, 0 = sync)
Clock X shift register (shifts on falling edge)
(output) Low 1st CLK_X pulse after last active column (low active)
Reset left Y shift register (low active, 0 = sync)
Clock left Y shift register (shifts on falling edge)
Low 1st CLK_YL pulse after last row
Parallel Y track & hold (1 = hold, 0 = track) apply pulse pattern - see sensor timing diagram
Column amplifier calibration pulse
1 = calibrate - see sensor timing diagram
Selects row indicated by left/right shift register high active (1= select row)
Apply 5 V DC for normal operation
Resets row indicated by left/right shift register high active (1 = reset)
Apply pulse pattern - see timing diagram
Use left or right register for SELECT and RESET
1 = left / 0 = right - see sensor timing
Activate viewfinder mode (1:4 sub sampling = 320 x 256 pixels) high active, 1 = sub
sampling
Control voltage for the DCREF voltage generation Connect to ground by default
Reference voltage (output), to be decoupled to GND
Should be about 1.2V, can be adjusted by DCCON

Anti-blooming drain control voltage

Default: connect to ground. The anti blooming is operational but not maximal.
Apply about 1 V DC for improved anti-blooming
The level of saturation can be adjusted by the voltage on
GND-AB. However, note also that this logarithmic part of the
response is not FPN corrected by the on-chip offset correction
circuitry.
The signal swing (and thus the dynamic range) is extended by
increasing the Vdd_reset (pins 59/79) To 5.5V. This is mode of
operation is not further documented.
