1 ADX-171p Miniature Analog Audio Demultiplexer

1.1 Introduction

The ADX-171p is a member of the picoLink family of miniature
products. The ADX-171p Analog Audio DEMUX is the world’s
smallest audio demultiplexer, packing both audio extraction and
20 bits quality D to A conversion in a very compact unit. The
ADX-171p can extract either AES pair from any of the 4 embed­ded audio groups in a 4:2:2 video stream. The full scale output
level (0 dBFS) can be set at 20, 22 or 24 dBU. The ADX-171p
provides a re-clocked serial digital output and is ideal for stand­alone monitoring and DEMUX application.

2 Overall view

Figure 2.1 illustrates the ADX-171p major parts and their loca­tions. The multiplexed signal is connected to the 4:2:2 IN BNC
and the re-clocked video signal is output through the OUT BNC.
The extracted audio channels are output through the two XLR
connectors; these connectors are labeled left and right for stereo
output.

3.1 Power Supply

The power supplies LKS-WSA and LKS-WSE, for 110V and 220V
operation respectively, are used to power the ASX-171p. Each
power supply provides a regulated +5VDC@750mA power
source. Plug the power supply into a wall or power bar outlet.
The ADX-171p uses a mini XLR-3 connector for its power needs;
figure 3.1 provides a detailed pinout of the male connector.

3.2 4:2:2 Input

Connect a 4:2:2 serial digital signal to the BNC labeled 4:2:2 IN.
The ADX-171p accepts a 4:2:2 serial digital video signal in either
525 or 625 lines format. The 4:2:2 signal must conform to the
SMPTE 259M-C standard.

Make sure that the 4:2:2 input signal cable has a maximum
length of 175 m (560’). Also ensure that all serial digital video
equipment are connected point-to-point. For instance, there
must be a point-to-point connection between the 4:2:2 IN BNC
and the source equipment. If a T-connector is used to connect
other equipment, the maximum specified cable length is no
longer valid.

Two monaural or one stereo analog audio signal is provided by
the XLR connectors. Figure 3.2 provides a detailed pinout of the
male connector.

4.1 Switch Settings

Figure 4.1 indicates the locations of the miniature switches at the
back of the ADX-171p.

Figure 4.1 ADX-171p Switches location

a c d

b

a- AES Selection

This slide switche selects the AES pair (pair 1 or pair 2) of audio
signal to extract.

b- Group Selection

Miniature slide switches provide group selection. Only one of the
4 groups should be switched On; in the event where more than
one group is switched On, the demultiplexing operation is per­formed by default on group 1. Switching all groups Off effective­ly disables all audio channels.

c & d- Level Attenuation

Each analog audio output level can be individually attenuated by
these slide switches. 3 levels of attenuation of the full scale out­put (0 dBFS) are provided: +20, +22 or +24 dBU.

4.2 Status LED

The bi-colored status LED, located next to the output cable, is
provided to identify any input error or power supply malfunction.
The following lists the possible situations:

Green: Indicates that the ADX-171p is powered and
has detected a valid 4:2:2 input signal.

Red: Indicates an error with the input signal has been

detected or simply, there is no input cable con­nected.

Off: The unit is not powered on. Check that it is

connected to the power supply, and the power
supply is properly connected to a power source.
