Abstract: An image sensor system includes an image sensor and a host controller. The image sensor includes a power input terminal, a data terminal, a clock input terminal, and a ground terminal. The host controller is coupled to the power input terminal to provide power to the image sensor, the data terminal to receive analog image data from the image sensor, the clock input terminal to provide a clock signal to the image sensor, and the ground terminal. The ground terminal serves as a common reference between the image sensor and one or more circuits of the host controller. The system also includes logic that is configured to transfer the analog image data from the image sensor to the host controller through the data terminal of the image sensor and to transfer one or more digital control signals between the image sensor and the host controller through the data terminal.
