NanEye GS

1. Nan Eye GS Sensor

1.1. Sensor Spectral Response

NanEye GS Responsivity at nominal gain is 12DN/nJ/cm² measured at 625 nm Wavelength.
If you need to convert it to V /lux-sec , let me add that NanEye is works at 10 bit resolution with a 1 V swing.  so you get 6.4V/lux-sec . 

Please look at the Spectral Response Graphic below :

Please look at the Relative Spectral Response Graphic below :

1.2. Power Consumption

NanEye GS -> Typical supply 3.3 V  .

 

Bias Current Config  Min Default Max Min Default Max Min Default Max
Main Clock (MHZ) 12.5 25 50
FPS 25 50 100
Power Consumption (mW)  83       100    115        93     110    135         103    120     145     

1.3. Integration/Exposure Time

The sensor exposure is defined through two 8 bit registers . 

  • Exposure_Time =TMCLK x 32 ⋅ ( REGPRE_SCALER X 2 + 2) x ( REGINT_TIME X 2 + 1 )
   Min  Max
REGINT_TIME 0x00 0xFF
REGPRE_SCALER 0x00 0xFF
MCLK Freq (MHz)  50  12.5 
MCLK Period (ns)  20 80 
Min Step 1.28us 5.12us
 Exposure_Time 1.28us 669778 us 
Exposure_Time with shutter at "0001" 1.28us+ 7.68us 670 ms

1.4. Deserealization

The Sensor Continuous data output Mode enabled by setting Register address 0x01 bit 7 = 0 is not available , so the training sequence between each row cannot be removed . This compromises the use of an (off the shelf) deserializer . Awaiba recommendation is to implement FPGA deserialization .   An alternative would be implement a Valid Line valid control signal  , since the Row training pattern is a fixed signal , this could be discarded for each row when reading the deserializer output signal  . 

FPGA recommendation:

  • FPGA Spartan 6 Family 

Deserializer recommendation:

  • National Semiconductor DS92LV1212A

 

 

1.5. Does NanEye GS has ROI ?

NanEye_GS has no ROI mode.

1.6. PWL mode

To activate the PWL function you must first activate it first by putting :

1º bit from Reg.0x03 -> 1


Then try this values with an image that has a area overexposed using default Gain and exposure values  :

PWLTimeGS Reg.0x07 -> 0xA0
PWLThrsGS Reg.0x08 -> 0xF1

1.7. ClK Termination resistor

We recommend to have 100 Ohms resistor on CLK differential line  .

2.2. CRA

This sensor lens has 0º Degree chief Ray Angle , the color filters are completely aligned with the pixel , meaning there is no physical CRA correction .
