SL23EP04SC-2 Equivalent & Substitute Parts

Part Overview

The SL23EP04SC-2 is a clock buffer IC manufactured by Skyworks Solutions Inc., designed for 220MHz clock distribution applications. This device features a 1:4 input-to-output ratio with LVCMOS output in an 8-SOIC package. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The SI53365-B-GT qualifies as a functional substitute based on the following alignment of critical parameters:

• Clock Distribution Function: Both devices operate as clock buffers with fanout capability
• Output Type: Both provide LVCMOS output
• Supply Voltage Compatibility: SI53365-B-GT supply range (1.71V ~ 3.63V) encompasses the SL23EP04SC-2 operating range (2.97V ~ 3.63V)
• Frequency Capability: SI53365-B-GT maximum frequency of 200 MHz supports applications within the SL23EP04SC-2 specification of 220 MHz
• Manufacturer Consistency: Both devices are manufactured by Skyworks Solutions Inc.
• Surface Mount Technology: Both use surface mount packaging

The primary differences are the input-to-output ratio (1:8 versus 1:4) and package type (16-TSSOP versus 8-SOIC), which represent functional enhancements and packaging alternatives rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The SI53365-B-GT is suitable as a substitute for the obsolete SL23EP04SC-2 in applications requiring clock distribution at frequencies up to 200 MHz with LVCMOS output. The substitute device is actively manufactured and complies with ROHS3 environmental standards, providing supply chain continuity and regulatory compliance advantages.

Design considerations for substitution include package footprint differences (8-SOIC to 16-TSSOP transition) and the increased output channel count (1:8 versus 1:4), which may require PCB layout modifications and firmware or hardware configuration adjustments. The extended operating temperature range (-40°C to 85°C) and improved moisture sensitivity rating (MSL 2 for 1 year versus MSL 2A for 4 weeks) represent functional improvements over the original specification.

Frequently Asked Questions (FAQ)

Q: Can SI53365-B-GT directly replace SL23EP04SC-2 without PCB modifications?

A: No. The package types differ (16-TSSOP versus 8-SOIC), requiring PCB footprint redesign. Pin assignments and signal routing must be verified against device datasheets before implementation.

Q: What is the frequency compatibility between these devices?

A: The SL23EP04SC-2 operates to 220 MHz, while SI53365-B-GT operates to 200 MHz. For applications requiring frequencies between 200-220 MHz, the substitute may not meet specifications. For applications at or below 200 MHz, the substitute is compatible.

Q: Does the 1:8 output ratio of SI53365-B-GT create compatibility issues?

A: The increased output channels represent a functional enhancement. Systems designed for 1:4 distribution can utilize the additional outputs or leave them unused. No incompatibility exists; however, PCB layout and signal integrity analysis are required.

Q: Are there supply voltage compatibility concerns?

A: Yes. The SL23EP04SC-2 requires 2.97V minimum, while SI53365-B-GT operates from 1.71V minimum. Both devices function within the 2.97V to 3.63V range. Verify that system power supply specifications align with both device requirements.

Q: What are the implications of the different MSL ratings?

A: SL23EP04SC-2 has MSL 2A (4-week shelf life), while SI53365-B-GT has MSL 2 (1-year shelf life). The substitute offers improved moisture handling and longer storage capability, reducing risk of moisture-induced failures during inventory management.

Q: Is ROHS3 compliance a factor in selecting the substitute?

A: Yes. SI53365-B-GT is ROHS3 compliant, meeting current environmental and regulatory requirements. The original part's compliance status is not specified. For applications subject to environmental regulations, the substitute provides documented compliance.
