Introduction
Overview
The SEA-9003 SDI Equalizing Amplifier is part of the GearLite 9000 digital
series of self-contained, small brick-format modules. The SEA-9003 is designed
for use in systems where signals of more than one digital standard are
distributed. The amplifier automatically equalizes up to 305m (1000ft) of
Belden 8281 input cable at 270Mbps, although 200m is the recommended limit
due to jitter considerations. Special measures have been taken to ensure
excellent return loss at both input and output. This guarantees error-free
performance with short cables.
The front panel of the SEA-9003 chassis provides visual performance indicators
with a power status LED and an input present status LED.
The SEA-9003 is delivered with a universal power adaptor and line cord
suitable for the country of use. Various mounting options are included that allow
a wide range of installation choices. The SEA-9003 provides a broadcast-quality
SDI distribution solution in a small, stand-alone package.
