Apparatus and method for clock recovery and eye diagram generation

摘要

A digital storage oscilloscope that has a port for receiving a signal, having an embedded clock signal, and a processor, configured by software to recover the embedded clock signal from the signal. In a preferred embodiment, the processor implements a digital PLL to recovered embedded clock signal. In a further preferred embodiment the processor uses the recovered embedded clock signal to generate an eye diagram that graphically portrays jitter in the data signal.
