Overview
The DEA-8205 is a two channel Multi-Definition SDI distribution amplifier, capable of
equalizing all common serial digital signals. Support for both standard-definition and
high-definition signals makes the DEA-8205 an extremely versatile SDI distribution amplifier.
Each channel of the DEA-8205 equalizes the incoming SDI signal, compensating for up to 300m
of cable at 270Mbps and over 120m of cable at 1.485Gbps. Both SDI channels provide 4 outputs
each. 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.
Features
The following features make the DEA-8205 the best solution for general SDI equalizing,
reclocking, and distribution:
• Two independent channels with 4 outputs each, total of 8 outputs
• Equalizes all SDI signals from 143 Mbps to 1.485 Gbps
• Equalizes up to 300m of Belden 1694A cable at 270 Mbps, or over 120m of cable at
1.485 Gbps
• LED indicators for signal presence on each channel
• Excellent input and output return loss exceeds SMPTE specifications
• Fits openGear DFR-8300 series frames
• 5 year transferable warranty
