Key Parameters

Substitute Part Grouping Explanation

Substitution of the GS2978-INE3 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 Equivalence: Both parts must serve the driver function for professional video applications using SMPTE standards with serial control interface.
• Mounting Type: Surface mount requirement must be maintained.
• Moisture Sensitivity: MSL rating of 3 (168 Hours) must be matched or exceeded to maintain handling and storage compatibility.
• Regulatory Compliance: RoHS compliance status ensures environmental and regulatory alignment.

The GS2988-INE3 meets all these substitution criteria and is identified as the manufacturer-recommended equivalent.

Parameter Comparison
