ABSTRACT:
Systems, methods and computer program products for capturing data. The methods include receiving an external clock signal having a first frequency, a first edge and a second edge. A clock period of the external clock period is the amount of time between any two successive first edges. The external clock signal is transformed into an internal clock signal based on the first edge and not the second edge of the external clock signal. Parallel data is received on a first plurality of signal links. The parallel data is received at a second frequency that is faster than the first frequency. The parallel data is captured using the internal clock signal.
