Key Parameters

Substitute Part Grouping Explanation

Substitution of the GS2978-CTE3 is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 16-VQFN Exposed Pad package in 16-QFN (4x4) form factor to ensure PCB footprint compatibility and surface mount assembly without redesign.
• Functional Classification: Both parts must operate as video driver ICs with serial control interface for SMPTE-compliant professional video applications.
• Manufacturer Consistency: Semtech Corporation maintains design continuity across the HD-LINX® series and related product lines.
• Electrical Specifications: Supply voltage range, MSL rating, and RoHS compliance must be maintained or exceeded.
• Interface Standards: Serial control interface and SMPTE standard compliance are non-negotiable for system integration.

The GS2988-INTE3 meets all substitution criteria as an active product within the same manufacturer's portfolio, offering direct functional replacement with identical package specifications.
