While digital audio has been around for over 25 years, only recently has there been an effort to standardize specifications. The Audio
Engineering Society (U.S.) and the European Broadcast Union have established an international standard, called AES/EBU. The detailed
specifications of this standard are:
Sampling Rate: from 32 KHz to 192 KHz
Bandwidth: from 4.096 MHz to 24.5 MHz
Impedance: 110O ± 20%

The key difference between twisted pair specifications for digital audio cable and standard analog audio cable is the impedance specification.
AES/EBU, with its broad tolerance, allows cables with impedances from 88 ohms to 132 ohms to be used. Standard analog audio cable impedance is 45 ohms to 70 ohms. This potential amount of mismatch can result in signal reflections and jitter, causing bit errors at the receiver. For this reason Belden recommends 100 to 120 ohm shielded twisted pair cable.

Belden’s product offering includes 110 ohm cable solutions and an entire line of single and multi-pair snake cable designed specifically
for digital audio. These cables utilize Datalene® premium grade high density insulation. This provides exceptional crush resistance as compared to standard foam polyethylenes, making the new cables less susceptible to damage resulting from cable pulling or flexing. The high velocity of propagation further reduces capacitance and signal delay providing error-free transmissions over extended distances.
