Abstract:
A method of transferring data between a first electrical component and a second electrical component, wherein the first electrical component and the second electrical component are both coupled to a common oscillator that oscillates at a first frequency, the method comprising the steps of:generating, at the first electrical component, a first bit stream having a second frequency that is a fraction of the first frequency and having a first number of bits; generating, at the first electrical component, an indicator signal having a third frequency that is a fraction of the first frequency; coupling, from the first electrical component to the second electrical component, the first bit stream and the indicator signal; sampling, at the second electrical component, the first bit stream and the indicator signal at a fourth frequency that is substantially identical to the second frequency, thereby recovering the first bit stream generated by the first electrical component; and aligning the sampling step based on the indicator signal.
