Abstract
A scanning system for use in an imaging apparatus includes a first light source and a second light source for emitting light beams for generating an image. A driver circuitry has first and second outputs connected to the first and second light sources, respectively, for controlling the first and second light sources. A signal transmitter includes a first interface for communicating a clock signal to the driver circuitry and a second interface for communicating an image information signal to the driver circuitry. During a clock cycle of the clock signal, the driver circuitry captures a first bit information from the image information signal at a rising edge of the clock signal and a second bit information from the image information signal at a falling edge of the clock signal. Thereafter, the driver circuitry drives the first and second light sources based on the first and second bit information captured, respectively.
