Overview
The SEA-8008 Serial Equalizing Amplifier is designed for general SDI equalizing and distribution use
where the outputs must all be non-inverted. It suits applications where multiple outputs are required,
but where reclocking is not required. Although the amplifier automatically equalizes up to 305m
(1000 ft.) of Belden 8281 input cable at 270Mb/s, 200m (656 ft.) is the recommended limit due to jitter
considerations. Special measures have been taken to ensure excellent return loss on both input and
outputs. This design guarantees error-free performance, even with short cable runs.
A very useful feature of the SEA-8008 is the card-edge LED status indicators, which confirm the
presence of an input signal capable of equalization.
The SEA-8008 operates on all serial digital standards, from 143Mb/s up to and including 360Mb/s. All
eight outputs are non-inverting, and so they can be used for the distribution of DVB/ASI signals, as
well as SMPTE 259M signals.
The SEA-8008 is designed to operate within the RossGear 8000-series digital products frame. Ten
amplifiers can be installed in a Ross 2-rack unit frame, and four amplifiers in a Ross 1-rack unit frame.
This amplifier also fits Leitch
