Modern audio recording, distribution and reproduction have become highly sophisticated and complex. Audio materials are mostly, if not all, are being converted to digital format, encoded and compressed onto various digital recording media. And to enjoy them, they are then decompressed, decoded, converted back to analog to drive your hi-fi system, computer speakers, headphone/earphones or simply playing back locally on your portable digital media players.
During the process of conversion to digital format a series of digital bits are generated, grouped into packets and recorded onto a desired media at precise timing intervals. Any disturbance or distortion of the timing precision degrades the accuracy of the recording. The amount of timing error allowed if the system is to meet its absolute performance requirement is on the order of 2 picoseconds, two trillionths of a second or 1/10,000,000 of the data interval. It takes very little to distort the wave enough to cause errors much larger than this.
The digital signals are transported from device to device using either optical connections, balanced AES digital connections or 75 Ohm precision coaxial connections. The 75 Ohm coaxial connections are the most common. Maintaining the 75 Ohm impedance through all of the connections is critical to getting the least timing distortion. Small dimensional fluctuations in the cable, imprecise termination or incorrect connectors will seriously compromise the timing accuracy by generating reflections that alter the voltages at critical points and times in the circuit. .
A.D.E.'s AES3id 75 Ohm Digital Audio Cable is engineered to support the requirements of the most demanding high sample rate audio data over S/PDIF or AES3id or for the lowest phase noise Word Clock applications. Pure silver center conductor provides the lowest possible resistive losses for the digital signal and its highly polished surface the lowest high frequency losses so the transitions are very highly defined. The foamed PTFE dielectric or insulation between the center conductor and the shield ensures the highest precision in the location and centering of the conductors to maintain the ultra precise impedance requirements of the cable. The high density dual shielding of silver-plated copper and dual-sided copper foil lowers the resistive losses in the shield, increasing the signal to noise ratio, including phase noise (or jitter) as well as reducing EMI/RFI interference.
