Visualize signal integrity: Optional jitter analysis
and real-time eye diagram analysis (Continued)
The real-time eye diagram with clock recovery is another
powerful and visual way to understand the signal integrity of your
waveforms (requires Option DSOX6JITTER). It quickly provides
information like eye width, eye height, and jitter and shows you
any signal anomalies. When you have an embedded clock or
explicit clock design, the real-time eye diagram might be the
only way to visualize what the input signal looks like from your
receiver’s perspective.
– Flexible clock recovery supporting
– Constant frequency
– First-order PLL (loop bandwidth)
– Second-order PLL (loop bandwidth and damping factor)

You can combine real-time eye diagram analysis with histogram
analysis to get further insight into your design.

embedded clock signal. The histogram indicates a bimodal distribution
and measured about 55-ps rms jitter.
