Dothinkey Launches Image Grabber for Testing Mobile Phone Camera Modules
The Image Grabber of this GSL20 has 2 sets of GND for each image sensor, in the case of not dividing the GND of the image sensor, DGND and AGND can be connected together with the GND of the image sensor; if the demand is to divide the GND of the image sensor, the digital ground of the image sensor is connected with DGND, and the analog ground of the image sensor or other GNDs are connected with AGND.
The internal pull-up resistor of GSL20's I2C pin is divided into 4.7K, 1.5K and 560R to connect to DOVDD, which can be configured into pull-up resistors with different values according to the actual application through the corresponding function, and the default is 1.5K pull-up resistor.
