T1
Start Exposure
The requirement to T1 should be from 10us to 1ms, a hardware debouncer circuit
shall be considered on the EXT_Trigger line.
Reserved External INPUT Pin
An external INPUT pin, EXT_INPUT is reserved for advanced user, it can be
functional with software customization applications. NRE fee shall be charged if need
us to enable this feature according to customers requirement.
The EXT_INPUT pin is opto-isolated, to driver the diodes, External input trigger signal
voltage should range 3.3V-24V, moreover the signal driving capacity should be more
than 60mA
.
Camera input signal internal circuit
Exposure_timing Pin Description
This pin is an output indicates the whole exposure period of the camera, polarity can
be predefined by software command. The internal circuit of this pin is open-drain, so
need a pull-up resistor circuit to enable the feature. The pull up voltage must follow
host system voltage level.
