Systems, methods and computer program products for high speed data transfer using an external clock signal

A system for capturing data, the system comprising:

• an external clock port for receiving an external clock signal having a first frequency, a first edge and a second edge, wherein a clock period of the external clock signal is the amount of time between any two successive first edges;
• a first plurality of signal link ports for receiving parallel data at a second frequency faster than the first frequency;
• and
• logic in communication with the external clock port and the first plurality of signal link ports for facilitating:
• transforming the external clock signal into an internal clock signal based on the first edge and not the second edge of the external clock signal, wherein the internal clock signal consists of any one of a first internal clock signal running at a second frequency, a plurality of second internal clock signals running at the first frequency wherein each second internal clock signal comprises a pulse such that the combination of clock pulses of the plurality of second internal clock signals constitute said second frequency, or a plurality of clock signals running at the second frequency;
• and
• capturing the parallel data using the internal clock signal.
