GS2972-IBTE3

Video Processing Overview

The GS2972-IBTE3 is a multi-rate SDI transmitter designed for professional video applications. It supports operation at 2.970Gb/s, 2.970/1.001Gb/s, 1.485Gb/s, 1.485/1.001Gb/s, and 270Mb/s. The device integrates complete SMPTE audio and video processing, including an embedded cable driver and support for up to eight channels of 48kHz audio. It complies with SMPTE ST 425M, ST 424M, ST 292M, and ST 259M-C standards. Powered by +1.2V digital and analog supplies, it operates within a temperature range of -20ºC to +85ºC in a compact 11mm x 11mm BGA package.

Video Processing Feature Summary

• Supports optional conversion from SMPTE ST 425M Level A to Level B formats
• Includes auxiliary data insertion capabilities
• Features automatic dual slew-rate selection for varying operational requirements

Video Processing Applications

• 1080p 50/60 cameras and camcorders
• Dual-link (HD-SDI) to single-link (3G-SDI) converters
• Multi-format audio embedding modules
• Multi-format digital VTRs and video servers
• 3Gb/s SDI test signal generators

Video Processing Procurement Notes

Verify the specific suffix IBTE3 against official Semtech documentation to confirm pinout compatibility and packaging details. Ensure the selected variant matches the required operating voltage and interface specifications for your design. Cross-reference the manufacturer's latest datasheet to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Video Processing Selection Notes

Select this component when a fully integrated SDI transmitter with embedded audio and cable driving capabilities is required. It is suitable for designs needing compliance with multiple SMPTE standards without external discrete components. Consider its low power consumption and small form factor for space-constrained professional broadcast equipment.

Video Processing Part Context

This device belongs to the GS2972 family of serial digital interface transmitters. It serves as a key component in professional video transmission systems, replacing traditional multi-chip solutions. The part consolidates serialization, clock recovery, and output driving into a single integrated circuit.

Video Processing Replacement Considerations

Direct substitutes include the GS2971A receiver counterpart for paired link designs. Other compatible parts in the series are the GS2970 and GS2960 receivers. Verify functional equivalence and pin compatibility before swapping.
