GS2984-INTE3Z

Video Processing Overview

The GS2984-INTE3Z is a high-speed BiCMOS integrated circuit designed as an adaptive cable equalizer for 75-ohm coaxial video signals. It supports SMPTE 424M, SMPTE 292M, and SMPTE 259M standards with data rates from 143Mb/s to 2.97Gb/s. The device features automatic cable equalization and DC restoration, enabling signal recovery over cable lengths up to 140m at 3Gb/s. It operates within a temperature range of -40°C to +85°C and consumes typically 195mW. The component is housed in a 16-pin, 4mm x 4mm QFN package.

Video Processing Feature Summary

• Automatic cable equalization compensates for signal attenuation over long coaxial runs without manual adjustment.
• Integrated DC restoration stage recovers signal content lost due to pathological test patterns in SDI streams.
• Carrier detect functionality allows direct connection to mute pins to silence output during signal loss.
• Footprint and drop-in compatible with existing GS2974 designs, requiring no additional application changes.

Video Processing Applications

• Professional video infrastructure utilizing 3G-SDI transmission
• Long-distance coaxial cable signal restoration in broadcast environments
• Multi-standard video processing systems supporting SD, HD, and 3G formats

Video Processing Procurement Notes

Verify the obsolete status indicated by distributor records before design finalization. Confirm that the GS2994 is adopted for new designs as per official guidance. Ensure the INTE3Z suffix matches the required tape and reel packaging quantity. Check RoHS compliance documentation for halogen-free encapsulation requirements.

Video Processing Selection Notes

Select this component when legacy compatibility with GS2974 footprints is mandatory. Choose the GS2984 for applications requiring specific DC restoration characteristics for pathological test patterns. Consider the GS2994 for new designs where longer reach or updated performance metrics are prioritized over pin-to-pin interchangeability.
