7700DA-HD SMPTE292M Re-Clocking Distribution Amplifier
1. OVERVIEW
The 7700DA-HD Distribution Amplifier provides an economical method of distribution for your
SMPTE 292M (1.5 Gb/s) HDTV serial digital signals. The 7700DA-HD has been designed to be used
primarily as a reclocking 1.5Gb/s distribution amplifier, however, it can also be used as a non-reclocking
SMPTE 310M (19.4 Mb/s, or 45 Mb/s), DVB-ASI, or SMPTE 259M(143 to 540 Mb/s) distribution product.
The DA’s come in two versions.
Model Total Outputs DVB-ASI Compatible Outputs Slots
7700DA-HD 4 4 1
7700DA8-HD 8 6 2
Features:
• Reclocking mode for SMPTE 292M (1.5 Gb/s) signals
• Non-reclock mode for SMPTE 310M (nominal 19.4 Mb/s), SMPTE 259M (143 to 540 Mb/s) or
DVB-ASI, or any other bit rate less than 1.5 Gb/s
• Fully hot-swappable from front of frame with no BNC disconnect required
• Polarity maintained from input to output for DVB-ASI applications (only outputs 1,2,3,4,5 and 7 on
7700DA8-HD)
• Automatic cable equalization to 130 m
• Tally output on Frame Status bus upon loss of input signal

2. INSTALLATION
The 7700DA-HD comes with a companion rear plate that has 5 BNC connectors. The 7700A10-HD
comes with a companion rear plate that has 9 BNC connectors and occupies two slots in the frame. For
information on mounting the rear plate and inserting the module into the frame see the 7700FR chapter
section 3.
Figure 2: Rear Panels
HD INPUT Input BNC connector for 10-bit serial digital video signals compatible with the SMPTE 292M
standard.
HD OUTPUT 7700DA-HD: There are four BNC connectors with reclocked serial component video
outputs, compatible with the SMPTE 292M standard. All outputs maintain the same polarity as
the input and are DVB-ASI compliant in non-reclock mode.
7700DA8-HD: There are eight BNC connectors with reclocked serial component video outputs,
compatible with the SMPTE 292M standard. Outputs 1, 2, 3, 4, 5 and 7 maintain the same
polarity as the input and are DVB-ASI compliant in non-reclock mode.

4. STATUS LEDS
MODULE OK This Green LED will be On when the module is operating properly
LOCAL FAULT This Red LED will be On when input video is lost or when there is a fault in the
module power supply.
CARRIER PRESENT: This Green LED will be On when there is a valid signal present at the module
input.
CABLE LENGTH WARNING: This Yellow LED will be On when the cable equalizer detects that the cable
length is greater than a preset threshold. (factory set for 125 meters of Belden 1694
or equivalent cable). See section 5.3 for information on adjusting the cable
equalizer warning threshold.
