The GS3490-INE3 is a low power cable equalizer from Semtech Corporation designed for SMPTE 424M, 292M, and 259M serial digital video signals. It compensates for cable losses when transmitting these signals, allowing for longer cable runs. This device is a key component in broadcast and professional video systems, ensuring signal integrity over extended distances.

Applications:

• Broadcast video equipment (e.g., cameras, switchers, routers)
• Digital video recording (DVR) and playback systems
• Professional video editing suites
• Video distribution amplifiers
• Security and surveillance systems employing SDI video

Features:

• Supports SMPTE 424M (3G-SDI), SMPTE 292M (HD-SDI), and SMPTE 259M (SD-SDI) standards
• Automatic cable equalization for different cable types
• Data rates from 270 Mbps to 2.97 Gbps
• Low power consumption
• Output return loss better than 15 dB
• Adaptive equalization to accommodate varying cable lengths

Benefits:

• Extended cable reach for SDI signals, minimizing the need for repeaters
• Improved signal quality and reduced jitter for cleaner video signals
• Simplified system setup with automatic cable equalization
• Energy efficient operation due to low power consumption
• Enhanced system reliability and performance

Additional Details:

The GS3490-INE3 automatically compensates for the effects of cable loss, maintaining signal integrity. It is designed for use with 75-ohm coaxial cables. The device operates from a single 3.3V power supply and incorporates features to minimize power consumption. Its performance is optimized for data rates up to 2.97 Gbps. The adaptive equalization mechanism adjusts to provide compensation suitable for the cable connected. The small form factor of this equalizer allows for easy integration into various equipment designs. The device is designed to meet stringent return loss specifications.
