Line1 (Opto-Isolated Output) Circuit - Daheng Imaging MARS 10GigE Series User Manual


Rising edge delay: <50μs (0°C~45°C), parameter description as shown in Figure 7-4

Falling edge delay: <50μs (0°C~45°C), parameter description as shown in Figure 7-4

Different environment temperature and input voltage have influence on delay time of opto-isolated input
circuit. Delay time in typical application environment (temperature is 25°C) is as shown in Table 7-4


Rising time delay (TRIGIN_R_DELAY): the response time from LINE0+ rises to 50% of amplitude to
INPUT0 decreases to 0.8V

Falling time delay (TRIGIN_F_DELAY): the response time from LINE0+ decreases to 50% of
amplitude to INPUT0 rises to 2V
