Image sensor and light source driver integrated in a same semiconductor package

A method, comprising:

• generating a first clock signal and a second clock signal with a timing circuit that is within a semiconductor chip package;
• generating a light source drive signal from the first clock signal with a light source driver circuit that is integrated within the semiconductor chip package;
• sensing visible light with visible light pixels of an image sensor that is integrated within the semiconductor chip package;
• and,
• generating depth information with depth pixels of the image sensor, the generating of the depth information comprising the image sensor receiving the second clock signal and receiving light generated with the light source drive signal.

A computing system, comprising:

• a plurality of general purpose processors;
• a system memory;
• a memory controller coupled between the system memory and the general purpose processors;
• an image sensor, a light source driver circuit and a timing circuit integrated in a same semiconductor chip package, said image sensor comprising visible light pixels and depth pixels, said depth pixels to sense light generated with a light source drive signal, said light source driver circuit comprising an output to provide said light source drive signal, said image sensor comprising an input to receive a first clock signal for said depth pixels, said timing circuit comprising a first output to provide said first clock signal, said light source driver circuit comprising an input to receive a second clock signal for said light source drive signal, said timing circuit comprising an output to provide said second clock signal.
