Timing and Readout of the Sensor
High Level Timing
The LUPA 3000 sensor is a pipelined synchronous shutter. This indicates that light integration and readout occur in parallel, achieving
the high frame rate and data throughput.
The maximum frame rate of the sensor is determined by the time needed to readout a full frame. This frame time is separated in the
FOT and the time to readout all lines. The readout of a line is separated in a ROT and the readout of all kernels.
Integration Timing
The integration time is controlled through the EXPOSURE_1 pin.
The rising edge of EXPOSURE determines the start of exposure
and the falling edge of EXPOSURE_1 starts the FOT and
determines the end of the integration time.
The falling edge of the internal pixel reset pulse causes a visible
crosstalk in the image, unless the edge occurs in the beginning
of the ROT during readout. As a result, the EXPOSURE pulse is
internally delayed until the next ROT. The duration of this delay
depends on the length of the line being readout. If the
EXPOSURE_1 is after Lx is finished, then integration starts
immediately. There is no need to wait for ROT.
The internal timing of the FOT is controlled by the sequencer.
The length of the FOT is set by the SPI registers
.

Ensure that pixel_reset is high for at least 3 µs.
FOT Starts After Readout
This is the normal situation where a full window is readout. A full
window refers to the resolution set by the Y_START, Y_END, and
NB_OF_KERNELS register. This may be the full resolution or a
partial window.
‘line x’.
When EXPOSURE_1 goes low, the FOT begins immediately.
Integration time continues until the falling edge of pix_sample.
The falling edge of pix_sample is a fixed amount of time after the
falling edge of EXPOSURE_1. This time is set SAMPLE_TIMER
