The test structures implemented in this image sensor are:
Spi_load (AH
then the data is internally available on the rising edge of
SPI_load.
Sh_kol (AL
It is used in sample and hold mode and binning mode.
Norowsel (AH
readout (see Timing and Readout of Image Sensor).
Pre_col (AL
to reduce row blanking time.
Voltage averaging (AH
voltage averaging of two pixels.
Array of pixels (6 x 12) that outputs are tied together:
used for spectral response measurement.
Temperature diode (2): Apply a forward current of
10 mA to 100 mA and measure the voltage V
diode. V
decreases with approximately 1.6 mV/°C).

point of the x-address and y-address is uploaded. This
downloaded starting point initiates the shift register in the
x-direction and y-direction triggered by the Sync_x and
Sync_y pulse. The minimum step size for the x-address and
the y-address is 2 (only even start addresses can be chosen).
The size of both address registers is 10-bits. For instance,
when the addresses 0000000001 and 0000000001 are
uploaded, the readout starts at line 2 and column 2.
To acquire a frame rate of 15 frames/sec, the output
The frame period of the LUPA4000 sensor is calculated as
Frame period = FOT + (Nr. Lines x (ROT + pixel period
FOT = 5 ms
Nr. Lines: Number of Lines read out each frame (Y)
Nr. Pixels: Number of pixels read out each line (X)
ROT = 200 ns (nominal; can be further reduced)
Pixel period: 1/66 MHz = 15.15 ns
Example read out of the full resolution at nominal speed
Frame period = 5 ms + (2048 x (200 ns + 15.15 ns x 2048)
