The multiplexer / de-multiplexer pair at a glance
The SDI-TD-3GMX-5 is a Flashlink time-division multiplexer (TDM) that either allows any
pair of supported HD-SDI or SD-SDI inputs or a single HD-SDI or SD-SDI input, plus up to
4 SD-SDI inputs to be transported over a single 3GHD-SDI link.
The SDI-TD-3GDX-5 is a Flashlink time division de-multiplexer that either recovers the 2
HD-SDI/SD-SDI streams or the single HD-SDI/SD-SDI stream plus 4xSD-SDI streams from
the 3GHD transport signal. The selection is automatic, based on what is detected in the
stream.
The HD-TD-3GMX-2 is a Flashlink time-division multiplexer (TDM) that allows any pair of
supported HD-SDI or SD-SDI inputs to be transported over a single 3GHD-SDI link.
The HD-TD-3GDX-2 is a Flashlink time division de-multiplexer that recovers the 2 HD-
SDI/SD-SDI streams from the 3GHD transport signal.
Other key features of the multiplexer / de-multiplexer pair include:

Supports all the most common video standards including SDTI.

Accepts any combination of synchronous or asynchronous HD-SDI 1485 Mbps or
SD-SDI 270 Mbps input formats, as long as the video standard is supported. Correct
video formats will be recovered at the de-multiplexer end.

Separate stream clock reference data for each channel is transferred for remote
clock regeneration. Correct clocks will be recovered at the de-multiplexer end.

Automatic input format detection for each channel.

All streams embedded in the 3GHD transport signal are completely independent. No
cross-contamination of the other stream when one input is lost.

Low latency.

Can be combined with SDI-TD-MUX-4 and SDI-TD-DMUX-4 modules to transport
up to 8 SD-SDI channels over one 3GHD link.

High performance optics for short and long haul applications available, including
CWDM and DWDM.

Optical and electrical 3GHD TDM outputs are available simultaneously from the
multiplexer cards, if purchased with an optional laser.

Change-over functionality between de-multiplexer electrical and optical inputs.

The transport signal is compliant with the SMPTE-425M Layer B standard and will
always be marked as 1080/30P. Standard 3GHD infrastructure can be used to
transport the multiplexed signal.

Multicon interface allows remote control, status monitoring, error reporting and
SNMP support.

The HD-TD-3GMX-2 and HD-TD-3GDX-2 can be field upgraded to the SDI-TD-
3GMX-5 and SDI-TD-3GDX-5 respectively if the need arises.
