At high enough speeds, digital starts looking like sine waves. 😕 Course, HDMI isn't quite there yet unless the latest stuff is bumping up against it.
This is a problem people who are doing PCB layout for RAM have to worry about. The traces have to be nearly the same exact length else the timing is off due to trace impedance. If you look at a PCB around memory chips, you'll see the traces doing little serpentines to try can keep the trace lengths the same.
