What makes a Digital Interconnect

How is 75 ohm measured and what makes a cable specifically digital?

I have a coax RCA cable with the following specs, which is sold as an analog:

Geometry: coax
Bandwidth: > DC - 1 GHz
Rs: center pin 0.06 Ω
ground 0.19 Ω
Cp: 56 pF (pin / shell)
Ls: center pin 1.6 μH
ground 1.6 μH
Bend Radius: 3” (75mm)
Cable Diameter: 3/16” (4.8mm)
Shielding: low magnitude 100% RF shielding, tied to shell at both end
Tolerance: 0.5%

Why a measurement of bandwidth?

For a moment there I felt quite safe... knowing I was out and you were in.... then I read the retired part.

I'm feeling less secure Now.
