Abstract
An apparatus and method for sampling a plurality of digital video signals to generate an interleaved digital video signal is disclosed. The apparatus includes: a first analog-to-digital converter (ADC), coupled to an analog input signal, for converting the analog input signal to a first digital output signal according to a sampling clock signal; a second ADC, coupled to the analog input signal, for converting the analog input signal to a second digital output signal according to the sampling clock signal; a reference clock generator, for generating a reference clock; a random signal generator, for outputting control values in a random sequence; and a clock controller, coupled to the reference clock generator and the random signal generator, for modifying the reference clock signal according to the control values to generate the sampling clock signal to the first ADC and the second ADC.
