Preamble
Overview
This document describes the interfacing and the driving of the
image sensor LUPA-1300, which is a 1280 by 1024 CMOS pixel
array working at 450 frames/sec. The sensor is an active pixel
sensor with synchronous shutter. The pixel size is 14 * 14 µm
and the sensor is designed to achieve a fame rate of 450
frames/sec at full resolution. This high frame rate can be
achieved by 16 parallel output amplifiers each working at 40 MHz
pixel rate.
The readout speed can be boosted by means of windowed
Region Of Interest (ROI) readout. High dynamic range scenes
can be captured using the double slope functionality.
The sensor uses a 3-wire Serial-Parallel Interface (SPI). It is
housed in a 145-pin ceramic PGA package.
In the following sections the different modules of the image
sensor are discussed more into detail. This data sheet allows the
user to develop a camera-system based on the described timing
and interfacing.

Figure 1
shows the spectral response characteristic. The curve
is measured directly on the pixels. It includes effects of
non-sensitive areas in the pixel, e.g., interconnection lines. The
sensor is light sensitive between 400 and 1000 nm. The peak QE
* FF is 15% approximately between 500 and 700 nm.

As one can see from
Figure 2,
the output signal ranges between
0 V to 1.1 V and is linear until around 800 mV. Note that the upper
part of the curve (near saturation) is actually a logarithmic
response.

Sensor Architecture
The image sensor consists of the pixel array, the column readout
electronics, X-and Y addressing, on-chip drivers, the output
amplifiers and some logic.
Notes
2. All parameters are characterized for DC conditions after thermal equilibrium has been established.
3. Unused inputs must always be tied to an appropriate logic level, e.g., either VDD or GND.
4. This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however it is recommended that normal precautions
be taken to avoid application of any voltages higher than the maximum rated voltages to this high impedance circuit.
5. All power supplies should be sufficiently decoupled because spikes and drops in the power supplies will be immediately visible in the analog output signals.
