1. OVERVIEW
The Evertz 7700DA6-L is an inexpensive 1x6 SD-SDI Distribution Amplifier with passive loop thru which
allows for cascading of multiple DA cards. It amplifies serial digital video signal at rates of 19.4 Mb/s and
143 Mb/s to 540 Mb/s.
The 7700DA6-L features an auto-equalized input with 6 reclocked outputs. The 7700DA6-L has been
designed for use as a SMPTE 310M (19.4 Mb/s), DVB-ASI, M2S or SMPTE 259M distribution product.
SMPTE 310M support is selected by setting a rate select jumper.
The 7700DA6-L occupies one card slot and can be housed in the 1RU 7701FR frame which holds up to
three single or dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU
350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
Features:
•Supports up to 540Mb/s operation.
•DVB-ASI compatible.
•Non-reclocking mode for SMPTE 310M.
•Features independent isolated output drivers to ensure no cross channel loading effects (i.e. no
need to terminate unused outputs).
•VistaLINK®- capable offering remote monitoring, control and configuration capabilities via SNMP.
VistaLINK®is available when modules are used with the 3RU 7700FR-C frame and a 7700FC.
•VistaLINK®Frame Controller module in slot 1 of the frame.
•Return loss > 15dB up to 540Mb/s.
•250m auto eq. at 270Mb/s (Belden 8281).
Outputs:
•6 reclocked outputs
•1 passive looping output
•Return loss > 15dB up to 540Mb/s
•Wide band jitter < 0.2 UI
Card Edge LEDs:
•Signal presence
•Module Health Status

2. INSTALLATION
The 7700DA6-L comes with a companion rear plate that occupies one slot in the frame. For information
on inserting the module into the frame see section 3 of the 7700FR chapter.
Figure 2-1: 7700DA6-L Rear IO Module
SDI INPUT:Input BNC connector for 10-bit serial digital video signals compatible with the
SMPTE 259M, DVB-ASI or SMPTE 310M standard. See section 5.3 for information on
selecting the correct video standard.
LOOP:The loop thru BNC connector for 10-bit serial digital video signals is compatible with the
SMPTE 259M or DVB-ASI standard. The output signal is the same as the input video
signal (without any reclocking). Refer to section 5.2 for information regarding loop thru
connections.
SDI OUTPUT:There are six BNC connectors with reclocked serial component video outputs,
compatible with the SMPTE 259M / DVB-ASI, or SMPTE 310M standard.

4. STATUS LEDS
The 7700DA6-L has seven LED Status indicators on the front card edge to show operational status of the
card at a glance. Figure 5-1 shows the location of the LEDs.
Two large LEDs on the front of the board indicate the general health of the module
LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence
of a valid input signal or if a local input power fault exists (i.e.: a blown fuse).
The LOCAL FAULT indication can also be reported to the frame through the
FRAME STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when a valid input
signal is present and board power is good.
There are five small LEDs that indicate the status of the equalizer and reclocker.
LOCK: This Green LED will be On when there is a valid signal present at the module
input.
RECLOCKER RATE: There are 5 LEDs that indicate the rate (143, 177, 270, 360 or 540 Mb/s) that
the reclocker is currently using when the Rate jumper is set to the 259M/344M
position.

5.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J15, located at the front of the module determines whether local faults (as
shown by the Local Fault indicator) will be connected to the 7700FR frame's global status bus.
FRAME STATUS: To monitor faults on this module with the frame status indicators (on the power
supply’s FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position.
When this jumper is installed in the Off position local faults on this module will not
be monitored.
5.2. CONNECTING LOOP THRU
The LOOP BNC connector is used to connect multiple 7700DA6-L modules to the same input video
signal. This is accomplished by connecting the LOOP connector of the source module to the IN
connector of the next module. This is repeated for the desired number of modules. The last module in
the looped chain MUST HAVE the LOOP connector terminated with 75Ω.

The last module in the looped chain MUST BE terminated with 75
Ω
.

The 7700DA6-L also has a termination jumper J2. To terminate the signal (for non-
looping applications), ensure that this jumper is installed otherwise leave open.
