Product overview
The SDI-TD-DMUX-4 is a Flashlink time division de-multiplexer where four SD-SDI or DVB-
ASI input signals are regained from the HD-SDI multiplexed input signal. There are both
optical and electrical HD-SDI input options. The input signal complies with the SMPTE
346M-2000 standard. Use the SDI-TD-MUX-4 board for generating the HD-SDI signal.

Main features
−
Accepts and automatically detects many SD-SDI 270 Mbps input stream formats as
well as 270 Mbps DVB-ASI, of which four streams of any mix are embedded in the
HD-SDI input signal.
−
Built-in routing switcher for allocating input streams to output connectors.
−
Independent input streams allow uninterrupted signal transport of remaining signals
on loss of stream data for one or more streams.
−
Separate stream clock reference data for each channel is received from the
multiplexer for individual clock regeneration per channel.
−
Optical or electrical 1.485 Gbps input HD-SDI signal.
−
High performance optics for short and long haul applications including CWDM
option.
−
The output signals will automatically be regained at same clock rate and format as on
the inputs on the multiplexer side.
−
EDH handling for the SD-SDI.
−
GYDA-SC interface allows remote control, status monitoring, error reporting and
SNMP support.
