MODULE OVERVIEW
The 5120 Dual Serial DA is a two-channel digital video distribution amplifier with four
outputs per channel. The 5125 is also a two-channel digital video distribution amplifier
that provides reclocking of the serial data stream, improving jitter performance. The two
output channels on each module provide distribution of a serial digital input signal to four
outputs with automatic input equalization.
Up to 300 meters of cable can be equalized locally on each module. Maximum cable length
can also be set and other module status parameters monitored remotely using the optional
Avenue Touch Screen Control Panel and the Avenue PC Control Application.
As shown in the block diagram below, each input signal passes through a serial equalizer
circuit. The signal strength of the equalized output is monitored by the module processor
for cable equalization and EQ warning information available to the user via the front
panel control indicator or through the optional Avenue control interfaces. The video in the
5125 passes through reclocking circuitry. The serial outputs are buffered then AC coupled
to the BNCs on the rear of the frame providing eight serial outputs for distribution.
Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by on-board regulator. The module is fused with a resettable fuse device. If
the fuse opens due to an overcurrent condition, the module will lose power. After pulling
the module, the fuse will reset automatically requiring no replacement fuse.
Module ID information (slot location, software version and board revision) can be
monitored by the optional frame System Control module and read using the optional
interfaces available.

APPLICATIONS
The 5120 and 5125 Dual Serial DA modules can be utilized in distribution applications
where a modest number of DAs are required. The two channel capability can save rack
space and cost.
5120 Dual Serial DA
The 5120 Dual Serial Distribution Amplifier is a two-channel non-processing DA with
cable equalization and signal detection. In the example below, the serial digital PGM and
PVW outputs of a digital switcher are distributed throughout a facility from the 5120 DA.
One PGM and PVW output is fed to a 5250 DAC for viewing the outputs on analog
monitors.
5125 Reclocking Dual Serial DA
The 5125 Reclocking Dual Serial Distribution Amplifier can be used in similar distribution applications where reclocking is required to reduce jitter from long cable runs or
unstable video sources.

INSTALLATION
Plug the 5120 or 5125 module into any one of the slots in the tray and install the plastic
overlay provided onto the corresponding group of rear BNC connectors associated with the
module location. Note that the plastic overlay has an optional adhesive backing for
securing it to the frame. Use of the adhesive backing is only necessary if you would like
the location to be permanent and is not recommended if you need to change module
locations. This module may be hot-swapped (inserted or removed) without powering down
or disturbing performance of the other modules in the system.
CABLING
Refer to the 3 RU and 1 RU backplane diagrams of the modules below for cabling instructions. Note that both modules have identical rear connectors. Unless stated otherwise, the
1 RU cabling explanations are identical to those given in the 3 RU diagram.
Connect one of the serial
digital signals to be distributed
to the Serial In A BNC.
The CONTROL 15-pin
D-connector is not used
in this application.
Connect serial digital output
destinations to the outputs at
BNCs Out 1 A - Out 4 A.
Connect one of the serial
digital signals to be distributed
to the Serial In B BNC.
