Synchronization Mode Four different modes may be defined under user control. The TRIG1 and TRIG2 signals may be used to trigger external events and to control the integration time. The Master clock is either external or internal clock.
Free Run Mode with Integration Time Setting The integration and readout periods start automatically and immediately after the previous period. The read-out time depends on pixel number and pixel rate.

The integration time is set by the serial line and should be higher than the read-out time (otherwise it is adjusted to the readout time). Figure 8-1. Timing Diagram 8.1.2 Triggered Mode with Integration Time Setting The integration period starts immediately after the rising edge of TRIG1 input signal. The Integration time is set by the serial line. This integration period is immediately followed by a readout period. The read-out time depends on pixel number and the pixel rate. Table 8-1.

Trigger and Integration Time Controlled by One Input The integration period starts immediately after the falling edge of TRIG1 input signal, stops immediately after the rising edge of TRIG1 input signal, and is immediately followed by a readout period. The readout time depends on pixel number and pixel rate
