Figure 1: Simplified block diagram of the FRS-3G-DUAL card
1.1 The core functionality
The FRS-3G-DUAL is two 3G-HDSDI frame synchronizers on one Flashlink board. The two
frame synchronizers share a common sync input, but are otherwise completely
independent. They can handle all common SD, HD, and 3G level A video standards, and
the two inputs need not have the same input frequencies or the same frame rates.
Maximum video delay is eight frames.
The FRS-3G-DUAL comes in the standard Flashlink form factor and it is designed to be
used with Multicon Gyda, the Nevion system controller. A subset of the configuration
parameters can also be controlled by onboard switches, enabling stand-alone operation.
1.2 Secondary functionality
1.2.1 De-glitcher
The FRS-3G-DUAL comes with a built-in de-glitcher for continuous and seamless output.
This will clean up line errors due to up-stream switching or other signal glitches. The output
even remains error-free with change of input formats.
1.2.2 Input change-over with fallback to internal generators
The FRS-3G-DUAL comes with an electrical SDI input per frame synchronizer core.
Sophisticated input selection logic can switch automatically between the physical input and
one of the internal generators.
1.2.3 Multiple SDI outputs
The FRS-3G-DUAL comes with a total of 4 BNC SDI outputs. Each of the two frame
synchronizer cores has one inverting and one non-inverting output.
1.2.4 EDH processing
The FRS-3G-DUAL always does EDH processing.

1.3 Product variants and how they differ
There are no lower-spec variants of the FRS-3G-DUAL, but there is a variant that only has
one of the two independent frame synchronizer cores enabled from the factory. This
manual also covers this single-channel version, as the user interfaces are identical apart
from the fact that the single-channel user interface doesn’t show the control surfaces for the
second frame synchronizer.
For frame synchronizers that only accept SD-SDI and/or HD-SDI input, see the FRS-SDI,
FRS-HD-DMUX, and FRS-HD-XMUX4 product families. For prices, please contact Nevion
or an authorized Nevion dealer.

2 How to get started
2.1 Power requirements
The absolute maximum power consumption for this module is 11.1 W. This figure varies
considerably with the combination of video standards used. If the module will always be
used with the same combination of input standards, the table below can be used to
determine the actual maximum power consumption, and to determine how many modules
can safely be used in one frame.
Note that the module will draw all its power from +5 V. Check the +5 V rating of
the power supply, generally it will be lower than the rating for the entire supply!
Table 1: Maximum power consumption as a function of the video standards used
The single-channel variant of FRS-3G-DUAL uses more than half the power of
a normal dual-channel unit, see table above!

The backplane for the FRS-3G-DUAL is labeled FRS-3G-DUAL-C1. It is designed to be
fitted in a Flashlink rack unit and to take up a single slot. The table below is an overview of
the connectors and their associated functions.
Table 2: Connector functions
Unused SDI inputs/outputs should be terminated with 75 Ohm.
2.2.1 Sync input
The main module features a slide switch to select between sync taken from the backplane
input (switch position marked “BP”) and a frame-distributed sync (switch position marked
“RACK”). At the time of writing this manual no frame-distributed sync is available, and the
switch should always be kept in the “BP” position.
The backplane also features a switch on the component side (the side facing into the
frame). This is a switchable termination for the backplane sync input. By setting the slide
switch (marked with a yellow box in Figure 2) to the left position like pictured, the sync input
is terminated to 75 Ohm. Generally, the sync inputs should be terminated if each sync input
is fed from a separate output of a distribution amplifier. On the other hand, if one sync
output is passively split and fed to several modules (via T-connectors), only one of the
modules should terminate the sync, the others should leave it unterminated.
If the module will be used without a sync frequency reference, the positions of these slide
switches do not matter.
2.2.2 GPI outputs (alarms)
The FRS-3G-DUAL hardware module has three GPI output lines. The first one, GPIO 0,
reflects the general status of the card, and thereby acts as an all-purpose alarm. GPIO 1
and GPOI 2 reflect the reclocker lock status of inputs 1 and 2, respectively. See Table 3
below for pin-out of the GPI lines.
2.2.3 GPI inputs
The FRS-3G-DUAL hardware module has four GPI inputs. No functions have yet been
assigned to these input lines.

2.3 What the LEDs mean
2.3.1 Exceptions/special conditions for the LEDS
The locate command will make all four LEDs blink on and off synchronously to quickly
identify the module in a larger installation. The condition of the card is not otherwise
affected by the command, only the appearance of the LEDs will change. The LEDs return to
their normal states and functions after the special locate condition has timed out.
