Overview
The DRA-8204 is a two channel Multi-Definition SDI distribution amplifier, capable of
equalizing and reclocking all common serial digital signals. Support for both standard-definition
and high-definition signals makes the DRA-8204 a universal SDI distribution amplifier.
Each channel of the DRA-8204equalizes the incoming SDI signal, compensating for up to 300m
of cable at 270Mbps and over 120m of cable at 1.485Gbps. The signal is then reclocked, with
automatic rate detection for all popular data rates. Each channel is fully independent and can run
at different data rates. LED indicators at the front of the card identify the presence of incoming
video and the identified signal data rate for each channel independently.
A special feature of the DRA-8204 is the ability to operate in a number of different channel
configurations. Dual channel mode is ideal for applications requiring only a few outputs, such as
mid-cable signal boosters, router expansion, or signal cleanup. Up to 20 SDI distribution channels
can be housed in a 2RU space. Special attention has been taken to ensure the SDI outputs
faithfully reproduce the incoming signals, with excellent jitter and return loss specifications.
LED indicators at the front of the card identify the presence of incoming video, simplifying
system troubleshooting.
