5. GLOSSARY
AES/EBU
This acronym covers the combined AES and EBU standard for transmission of digital
audio. The standard defines a serial interface known as AES3 as per AES, EBU 3250-E as
per EBU or ITU-R BS.647-2 as per ITU. The interface originally transmitted two channels
(one pair) with PCM coding with a bit depth of 20 or 24 bit and a sampling frequency
between 32kHz and 192kHz. Today the interface is also used as a framework to
transmit digital signals that may or may not be audio with linear PCM encoding. The
physical interface defined by the original AES/EBU standard was a 110 ohm balanced
line. The AES3-id standard later defined the physical interface as a 75 ohm coaxial cable.
BNC
Bayonet Neill-Concelman connector.
GNSS
Global Navigation Satellite System. Satellite navigation system with global coverage.
PLL
Phase Locked Loop. A feedback loop that synchronizes the phase of two signals.
PTP
Precision Time Protocol. Is a protocol used to synchronize clocks throughout a computer
network originally defined in the IEEE 1588-2002 standard.
