Photoelectric conversion device, camera module, endoscope, endoscope system, and apparatus

Abstract

A photoelectric conversion device is provided. The device includes a pixel array in which pixels are arranged, a drive controller configured to drive the pixel array, a horizontal transfer unit configured to sequentially output analog signals respectively output from columns of the pixel array, an AD converter configured to convert an analog signal output from the horizontal transfer unit into a digital signal, a first clock generator configured to generate a clock signal used to control an operation of the drive controller, and a second clock generator configured to generate a clock signal used to control the horizontal transfer unit and the AD converter. A clock tree in which a clock signal is distributed from the first clock generator and a clock tree in which a clock signal is distributed from the second clock generator form clock trees different from each other.
