Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL2305SI-1HT is determined by the following critical parameters:

• Frequency Capability: The substitute must support the maximum operating frequency of 140 MHz or higher
• Input/Output Configuration: Clock input with LVCMOS output compatibility
• Supply Voltage Range: Compatibility with 3.0V to 3.6V operation
• Operating Temperature Range: Support for -40°C to 85°C
• Mounting Type: Surface mount technology
• Package Compatibility: Physical and electrical compatibility with 8-SOIC or alternative surface mount packages

The SI53365-B-GTR meets these substitution criteria with enhanced specifications, including higher frequency capability (200 MHz), expanded supply voltage range (1.71V to 3.63V), and improved availability as an active product.

Parameter Comparison

Engineering Selection Recommendations

The SI53365-B-GTR is the designated substitute for the obsolete SL2305SI-1HT. Both devices are manufactured by Skyworks Solutions Inc. and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring regulatory compliance consistency.

The SI53365-B-GTR provides superior specifications across multiple parameters: maximum frequency increases from 140 MHz to 200 MHz, supply voltage range expands from 3.0V–3.6V to 1.71V–3.63V, and the device maintains active product status with extended moisture sensitivity protection (1 Year versus 4 Weeks).

The primary design consideration is package transition from 8-SOIC to 16-TSSOP, which requires PCB layout modification. The increased output ratio (1:8 versus 1:5) provides additional distribution capability without functional limitation for applications requiring only five outputs.

Frequently Asked Questions (FAQ)

Q: Can SI53365-B-GTR directly replace SL2305SI-1HT without circuit modification?

A: The SI53365-B-GTR is functionally compatible but requires PCB layout changes due to package differences (8-SOIC to 16-TSSOP). Pin assignments and electrical characteristics are compatible within the specified operating parameters.

Q: What is the impact of the increased input:output ratio (1:8 versus 1:5)?

A: The SI53365-B-GTR provides three additional output channels. Unused outputs can be left unconnected without affecting device operation or the five required outputs.

Q: Are there supply voltage compatibility concerns?

A: The SI53365-B-GTR operates across 1.71V to 3.63V, which fully encompasses the SL2305SI-1HT range of 3.0V to 3.6V. No supply voltage adjustment is required.

Q: How does the 200 MHz maximum frequency affect existing 140 MHz designs?

A: The higher frequency capability of SI53365-B-GTR is backward compatible. Designs operating at 140 MHz will function within the SI53365-B-GTR specifications with no performance degradation.

Q: What are the moisture sensitivity implications?

A: SI53365-B-GTR provides extended moisture protection (1 Year at MSL 2 versus 4 Weeks at MSL 2A), reducing handling and storage constraints during manufacturing and inventory management.

Q: Are regulatory certifications equivalent between the two parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory treatment in export and compliance documentation.
