Model 7125
HD/SD/ASI Dual
Reclocking DA
Data Pack
Revision 2.1 SW v2.2.1

MODULE OVERVIEW
The 7125 module is a dual-rate, serial digital distribution amplifier with automatic cable
equalization and reclocking. It automatically detects and handles 270 Mb/s Standard
Definition signals (525 or 625), 1.485 Gb/s High Definition signals, ASI data signals, and
allows passing of embedded audio. The module provides two DAs on the one module with
two sets of one serial digital input to four serial digital video outputs.
As shown in the block diagram below, the serial input signal passes through a serial
equalizer circuit where cable equalization and input monitoring is done. This output
signal then passes to a reclocking circuit. Here the serial input signal is locked to a local
serial clock removing timing noise and improving jitter performance.
The output of the reclocker circuit feeds into output drivers which provide four HD or SD
SDI serial digital outputs to the rear BNCs for distribution. When an ASI input is used
two outputs are provided.
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.
The on-board CPU can monitor and report module ID information (slot location, software
version and board revision), power status, and ancillary data status to the optional frame
System Control module. This information can be accessed by the user or set to register an
alarm if desired using the remote control options available.
Modules at software version 2.2.0 or later support SNMP (Simple Network Management
Protocol) monitoring. For each applicable signal processing module, module, signal, and
reference status are reported. For complete details on using SNMP monitoring, refer to
the Avenue System Overview in the manual that accompanies each frame.

APPLICATIONS
High Definition Distribution
The 7125 module can be utilized to distribute an HD, SD or ASI signal. Some typical uses,
such as distribution to an HD monitor, waveform monitoring equipment, and switcher
inputs, are shown in the block diagram below. The signal is reclocked to reduce noise and
jitter and allows distribution to any destination required. Destinations might include
other Avenue modules for video processing, HD up/down conversion conversion, or
embedding or disembedding of audio and many other functions
In addition, the 7125 module can also provide distribution of a calibrated high definition
signal throughout the facility from a 7405 HD Test Signal Generator when required. .

INSTALLATION
Plug the 7125 module into any one of the slots in the 1 RU or 3 RU frame 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 module below for cabling
instructions. Note that unless stated otherwise, the 1 RU cabling explanations are
identical to those given in the 3 RU diagram.

MODULE CONFIGURATION AND CONTROL
There are no configuration parameters that require setting on the 7125 module. Status of
the module can be monitored remotely using one of the Avenue remote control options or
locally using the module front panel controls.
If you are not using a remote control option, the module status can be monitored from the
front panel LEDs illustrated in the Front Panel Control and Indicators section below.
For monitoring the parameters remotely using the Avenue PC option, refer to the Avenue
PC Remote Configuration section of this document.
For monitoring the parameters remotely using the Avenue Touch Screen option, refer to
the Avenue Touch Screen Remote Configuration section of this data pack following
following Avenue PC.
For monitoring the parameters remotely using the Avenue Express Control Panel option,
refer to the Avenue Avenue Express Panel data pack that accompanies the option.
Front Panel Controls and Indicators
Each front edge indicator and switch setting is shown in the diagram below:

7125-6
SD IN green LED:
ON indicates SD signal is
present and equalized for all
outputs.
OFF indicates no SD input or the
signal may not be present or
cable equalization exceeds
maximum length allowed.
Pwr green LED:
Indicates the presence (ON) or
absence (OFF) of power (+5V).
Run green LED:
OFF:
A power fault of halted CPU
ON:
A halted CPU
FAST BLINK:
CPU Run error
SLOW BLINK:
System OK. (If SPI control is
active from the main frame
System Control Module, all
Run indicators will be syn-
chronized.).
HD IN green LED:
ON indicates HD signal is
present and equalized for all
outputs.
OFF indicates no HD input or
the signal may not be present or
cable equalization exceeds
maximum length allowed.
(There is no indicator for
ASI signal presence.)

TROUBLESHOOTING
As a troubleshooting aid, the signal presence, power and CPU status can be easily
monitored from the front panel of this module using the indicators explained in the Front
Panel Switches and Indicators section.
The following status items can be monitored using the Avenue Touch Screen Control
Panel, Express Panel, or PC Application:
• Input Status
• Slot ID, Software Version and Board Revision
Refer to the overall troubleshooting tips given below for the module:
No status lights are lit on front panel:
• Check that frame power is present (green LED{s} on frame power supplies).
• Check that module is firmly seated in frame. Try removing it and plugging
it in again.
Can’t control module:
• Check status of CPU Run green LED. Should be blinking slowly and in
unison with other modules if System module is present. If not, try removing
it and plugging it in again.
• System module may not be working properly if installed.
No signal out of module:
• Check status of SD In or HD In green LEDs. One should be lit. If not,
check the input signal for presence and quality.
• Check cabling to input of module.
