GS1561-CFE3 Equivalent & Substitute Parts

Part Overview

The GS1561-CFE3 is a video deserializer IC manufactured by Semtech Corporation, designed for professional video applications utilizing DVB-ASI and SMPTE standards. This component operates as a serial deserializer in the HD-LINX® II series and is housed in an 80-LQFP (14x14) surface mount package.

The GS1561-CFE3 has reached obsolete product status. Locating equivalent or substitute components is necessary for ongoing system maintenance, legacy equipment repairs, and design updates where continued availability cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GS1561-CFE3 is determined by the following critical parameters:

• Functional Compatibility: The substitute must support DVB-ASI and SMPTE standards for professional video signal processing
• Voltage Supply Range: The substitute must operate within compatible supply voltage specifications
• Package and Mounting: Physical form factor and surface mount capability must align with PCB design constraints
• Moisture Sensitivity: MSL rating must meet or exceed the original component's environmental requirements
• Manufacturer Support: Preference for components from the same manufacturer (Semtech Corporation) within the same product family

The GS2970-IBE3 is identified as a manufacturer-recommended substitute. While it differs in function (receiver vs. deserializer), package type (100-LBGA vs. 80-LQFP), and control interface (logic vs. serial), it maintains compatibility with the same professional video standards and supply voltage operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The GS2970-IBE3 is the manufacturer-recommended substitute for the GS1561-CFE3. Both components are manufactured by Semtech Corporation and support DVB-ASI and SMPTE standards for professional video applications.

Key considerations for selection:

• Functional Difference: The GS2970-IBE3 operates as a receiver with logic-level control interface, whereas the GS1561-CFE3 functions as a deserializer with serial control. System architecture must accommodate this functional distinction.
• Package Transition: Migration from 80-LQFP to 100-LBGA requires PCB redesign. The 100-LBGA package (11x11) differs significantly from the 80-LQFP package (14x14) in footprint and pin configuration.
• Voltage Supply: The GS2970-IBE3 supports dual voltage ranges (1.71V ~ 1.89V and 3.13V ~ 3.47V), providing greater flexibility than the GS1561-CFE3 single range (1.65V ~ 1.95V).
• Product Status: The GS2970-IBE3 carries "Not For New Designs" status, indicating limited future availability. Both components are in end-of-life phases.
• Compliance: The GS2970-IBE3 is RoHS Compliant, whereas RoHS status for the GS1561-CFE3 is not specified.

Frequently Asked Questions (FAQ)

Q: Can the GS2970-IBE3 directly replace the GS1561-CFE3 without PCB modification?

A: No. The GS2970-IBE3 uses a 100-LBGA (11x11) package, while the GS1561-CFE3 uses an 80-LQFP (14x14) package. PCB redesign is required to accommodate the different footprint and pin layout.

Q: What is the primary functional difference between these components?

A: The GS1561-CFE3 is a deserializer with serial control interface, while the GS2970-IBE3 is a receiver with logic-level control interface. System firmware and control logic must be adapted accordingly.

Q: Are both components suitable for new designs?

A: No. The GS1561-CFE3 is obsolete, and the GS2970-IBE3 is marked "Not For New Designs." Both components are in end-of-life status. For new designs, consult Semtech Corporation for current-generation alternatives within the HD-LINX® II series or successor product families.

Q: Do both components meet the same moisture sensitivity requirements?

A: Yes. Both the GS1561-CFE3 and GS2970-IBE3 have MSL rating 3 (168 Hours), indicating identical moisture sensitivity handling requirements during storage and assembly.

Q: What voltage ranges must be supported for substitution?

A: The GS1561-CFE3 operates at 1.65V ~ 1.95V. The GS2970-IBE3 supports 1.71V ~ 1.89V and 3.13V ~ 3.47V. System power supply design must accommodate the substitute's voltage requirements.

Q: Is the GS2970-IBE3 RoHS compliant?

A: Yes. The GS2970-IBE3 is RoHS Compliant. RoHS status for the GS1561-CFE3 is not specified in available documentation.
