The Semtech GS2986-INE3 is a multi-rate SDI adaptive cable equalizer. It's designed to compensate for signal loss caused by long coaxial cables in broadcast and professional video applications. It supports multiple SDI standards, ensuring compatibility with a variety of video formats.

Applications:

• SDI cable equalization in broadcast video equipment
• Compensating cable loss in video routers and switchers
• Extending transmission distance in CCTV systems
• Video distribution networks
• SDI signal conditioning

Features:

• Automatic cable equalization for SMPTE 424M, SMPTE 292M, SMPTE 259M and DVB-ASI standards
• Supports data rates up to 3Gbps
• Adaptive equalization, automatically adjusts to cable length
• Low power consumption
• Integrated output driver
• Cable length indicator

Benefits:

• Extends the usable length of SDI cables
• Maintains signal integrity and reduces jitter
• Simplifies system design with automatic equalization
• Reduces manual adjustment requirements
• Improved video quality, especially over long distances
• Compatibility with multiple SDI standards

Additional Details:

The GS2986-INE3 dynamically adjusts its equalization characteristics to counteract cable attenuation, which increases with frequency. This allows the device to maintain a high-quality signal even after significant cable loss. The adaptive nature of the equalizer means that it can automatically compensate for different cable types and lengths, simplifying system setup and eliminating the need for manual adjustments. The integrated output driver ensures a clean and stable signal output. The GS2986-INE3 is commonly used in environments where high-quality video transmission over long distances is essential.

The typical specifications include support for SMPTE standards like 424M (3G-SDI), 292M (HD-SDI), and 259M (SD-SDI), as well as DVB-ASI. The equalization range is usually specified for different types of coaxial cables, providing clear guidance on cable length limitations. The GS2986-INE3 typically operates on a single power supply voltage. Its low power consumption minimizes the impact on the overall system power budget.
