Inputs
SD/HD-SDI: Two electrial inputs (J9 and J10)
• Input equalization (Belden 1694A cable)
90m for 3 Gb/s (Input 1, J9)
100m for 3 Gb/s (Input 2, J10)
140m for 1.5 Gb/s
400m for 270 Mb/s

Outputs
SD/HD-SDI: Eight reclocked electrical outputs (in four
output pairs: J1/J2, J3/J4, J5/J6 and J7/J8)
• Return loss: >15 dB up to 1.5 Gb/s,
>10 dB to 3 Gb/s
• Signal level: 800 mV ±10%
• Output jitter (for inputs conforming to SMPTE 259M
and 292M standards):
<0.2 UI >100 kHz for 3G
<0.2 UI >100 kHz for HD
<1.0 UI 10 Hz – 100 kHz for HD
<0.2 UI 10 Hz – up for SD
The 8943RDA-D is a dual input SD/HD/3G-SDI
reclocking distribution amplifier. It provides two
electrical inputs that can be mapped to feed
any of four reclocked electrical output pairs
(one input per output pair). The module is also
completely DVB ASI compliant.
It can distribute either HD/3G-SDI or SD-SDI,
making it ideal for mixed format applications or
installations where an upgrade to HD/3G-SDI
is planned. Up to 90 meters for input 1 (J9),
100 meters for input 2 (J10) of Belden 1694A
cable can be equalized for HD/3G-SDI and up
to 440 meters for SD-SDI.
All parameters can be configured directly
from the card edge or via a standard HTML
Web browser when the 8900NET (Net Card)
Network Interface module has been installed.
The module operation and configuration, as
well as the signal presence and format, can
be monitored using industry standard SNMP
protocol via the 8900NET (Net Card) module.

Reclocking: Active/bypass
Input format selection: Auto/manual
Input to output mapping: Both inputs are active at
the same time and are configurable to any output pair
(one input per electrical output pair).
