ICS853310AVLF Equivalent & Substitute Parts

Part Overview

The ICS853310AVLF is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Renesas Electronics Corporation, designed for 2:8 clock distribution at frequencies up to 2 GHz. This device features differential inputs and outputs, supporting multiple input standards including CML, LVDS, LVPECL, and SSTL, with ECL and LVPECL output options. The component is housed in a 28-LCC (J-Lead) package for surface mount applications.

The ICS853310AVLF is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICS853310AVLF must satisfy the following critical parameters to ensure functional compatibility:

• Ratio - Input:Output: Must be 2:8 (two inputs, eight outputs)
• Differential Configuration: Both inputs and outputs must be differential (Yes/Yes)
• Package / Case: Must be 28-LCC (J-Lead) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -40°C ~ 85°C
• Supply Voltage Range: Must overlap or be compatible with 3V ~ 3.8V

The substitute parts identified are the SY100E310LJY and SY100E310LJY-TR, both manufactured by Microchip Technology. These parts maintain the same 2:8 differential fanout buffer architecture and 28-LCC package footprint. While the maximum frequency specification is reduced to 800 MHz (compared to 2 GHz for the original part), both substitutes support the required differential input and output standards (LVPECL) and operate within the specified temperature and voltage ranges. The primary difference between the two substitutes is packaging format: tube versus tape & reel.

Parameter Comparison

Engineering Selection Recommendations

The SY100E310LJY and SY100E310LJY-TR are active, in-production alternatives to the obsolete ICS853310AVLF. Both Microchip substitutes maintain identical 2:8 differential fanout buffer functionality and 28-LCC package compatibility, ensuring direct mechanical and electrical substitution at the board level.

Key compliance advantages of the Microchip substitutes include ROHS3 compliance and improved moisture sensitivity ratings (MSL 2 versus MSL 3), providing enhanced reliability for long-term storage and manufacturing processes.

Selection between SY100E310LJY and SY100E310LJY-TR depends on procurement and assembly requirements: the tube-packaged SY100E310LJY suits lower-volume applications, while the tape & reel variant SY100E310LJY-TR is optimized for high-volume automated assembly.

Frequently Asked Questions (FAQ)

Q: Can the SY100E310LJY directly replace the ICS853310AVLF without circuit modifications?

A: Yes, both parts share identical 2:8 differential fanout buffer architecture, 28-LCC package footprint, and operating temperature range. The mechanical and electrical interfaces are compatible for direct substitution at the board level.

Q: What is the impact of the reduced maximum frequency specification (800 MHz versus 2 GHz)?

A: The frequency reduction applies only to the maximum rated operating frequency. If your application operates at frequencies below 800 MHz, the Microchip substitute is fully qualified. Applications requiring operation above 800 MHz require alternative solutions.

Q: Are there differences in input and output signal standards between the original and substitute parts?

A: The ICS853310AVLF supports CML, LVDS, LVPECL, and SSTL inputs with ECL and LVPECL outputs. The SY100E310LJY supports LVECL and LVPECL inputs with LVECL and LVPECL outputs. Both parts support LVPECL, which is the common standard. Verify your circuit uses compatible signal standards before substitution.

Q: What is the difference between SY100E310LJY and SY100E310LJY-TR?

A: Both parts are electrically identical. The difference is packaging format: SY100E310LJY is supplied in tubes for manual or low-volume handling, while SY100E310LJY-TR is supplied in tape & reel format for automated pick-and-place assembly equipment.

Q: Are the Microchip substitutes RoHS compliant?

A: Yes, both SY100E310LJY and SY100E310LJY-TR are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What are the moisture sensitivity implications for storage and handling?

A: The Microchip substitutes have MSL 2 rating (1 year floor life) compared to MSL 3 (168 hours) for the original part. This provides extended storage capability and reduced risk of moisture-related failures during manufacturing.
