Abstract:
1. A method for capturing data, the method comprising: 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, and the external clock signal is received at an external clock port; 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; receiving parallel data at a first plurality of signal link ports, wherein the parallel data is received at a second frequency faster than the first frequency; and capturing the received parallel data using the internal clock signal, wherein the internal clock signal consists of any one of a first internal clock signal running at the 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.
