Table 9. INTEGRATION AND FRAME TIMING PARAMETERS

Name

Description

line_time

Duration of one line, expressed in logic clock cycles.

The minimum line time shall be dictated by the A/D conversion time and readout time (whichever

is larger).

frame_length

Defines the total frame time as frame_length * line_time logic clock periods. This parameter

needs to be configured large enough such that both the integration control operations (i.e. SFOT,

EFOT and configured integration time) and the readout operations (ROI readout + black lines)

can happen.

integration_coarse

Defines the coarse part of the integration time. Total integration time in logic clock periods is inte-

gration_coarse * line_time + integration_fine

integration_fine

Defines the fine part of the integration time. Total integration time in logic clock periods is integra-

tion_coarse * line_time + integration_fine

integration_offset_coarse

Offset between the Sequencer induced SFOT period and the start of the SFOT, expressed in line

periods.

The total integration offset time, expressed in logic clock cycles, is defined as integration_off-

set_coarse * line_time.

This parameter allows to increase the latency between a trigger event and the effective start of

integration in triggered modes.

The frame parameters and their relations are depicted in

Figure 16 below. Note that the green area depicts the readout

of regular lines (black reference / ROI defined image lines),

while the grey area represents the access to dummy lines (no

image data). The shaded green part represents the line

periods during which the control and datapath pipeline is

flushed.

Minimum integration time limitations are listed in

Table 10.
