1 ADX-172p Miniature Dual AES/EBU Audio Demultiplexer
1.1 Introduction
The ADX-172p/75/110 are members of the picoLink family of
miniature products. The ADX-172p is a miniature AES/EBU
demultiplexer capable of extracting 2 AES/EBU signals (4 audio
channels) from a 4:2:2 video signal. The ADX-172p is available
in both 75
Ω unbalanced (ADX-172p/75) and 110Ω balanced
(ADX-172p/110) AES/EBU output version. The ADX-172p can
extract any of the four embedded audio groups in a serial 4:2:2
video stream and provides a re-clocked serial digital output. The
low cost and compact packaging of the ADX-172p make it ideal
for standalone application.
