Image Resolution (X*Y)
Eos_x: end of scan signal: is an output signal, indicating when
the end of line is reached. It is not generated when
windowing.
Eos_y: end of scan signal: is an output signal, indicating when
the end of frame is reached. It is not generated when
windowing.
Eos_spi: output signal of the SPI to check if the data is
transferred correctly through the SPI.

Frame Rate and Windowing
Frame Rate
To acquire a frame rate of 15 frames/sec, the output amplifier
should run at 66 MHz pixel rate or two output amplifiers should
run at 33 MHz each, assuming an ROT of 200 ns.
The frame period of the LUPA 4000 sensor is calculated as
follows:
Frame period = FOT + (Nr. Lines × (ROT + pixel period × Nr.
Pixels) with:
FOT = 5 μs
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 (66 MHz
pixel rate):
Frame period = 5 µs + (2048 × (200 ns + 15.15 ns × 2048)
= 64 ms ≥ 15 fps.
ROI Readout (Windowing)
Windowing is achieved by an SPI in which the starting 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.
