ICS853111AYLF Equivalent & Substitute Parts

Part Overview

The ICS853111AYLF is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Renesas Electronics Corporation, designed for 2:10 clock distribution at frequencies up to 3 GHz. This device accepts differential inputs in CML, LVDS, LVPECL, or SSTL formats and provides ECL or LVPECL differential outputs in a 32-LQFP surface mount package.

The ICS853111AYLF is classified as obsolete. Equivalent substitute parts are available from onsemi in the MC100LVEP series, which maintain functional and electrical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICS853111AYLF with MC100LVEP series parts is based on the following matched electrical and mechanical parameters:

• Functional Equivalence: Both the ICS853111AYLF and MC100LVEP111 devices are 2:10 clock fanout buffers with identical input-to-output ratios and differential signal handling.
• Frequency Compatibility: Maximum operating frequency of 3 GHz is maintained across all parts.
• Package Compatibility: All parts use 32-LQFP (7x7) surface mount packaging, ensuring PCB layout compatibility.
• Operating Temperature Range: Identical -40°C to 85°C operating range across all parts.
• Signal Format Support: MC100LVEP111 devices support ECL, HSTL, LVDS, and PECL inputs, with ECL and PECL outputs. This encompasses the input and output formats of the ICS853111AYLF.
• Supply Voltage: MC100LVEP111 operates within 2.375V to 3.8V, which is a subset of the ICS853111AYLF range (2.375V to 5.25V). This represents a tighter specification suitable for modern low-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

The MC100LVEP111 series from onsemi provides direct functional substitution for the obsolete ICS853111AYLF. Both MC100LVEP111FAG and MC100LVEP111FARG are active products with identical electrical specifications and package compatibility.

Selection between the two onsemi variants depends on procurement and assembly requirements:

• MC100LVEP111FAG is supplied in Tray packaging, suitable for lower-volume applications or manual assembly processes.
• MC100LVEP111FARG is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly and pick-and-place operations.

Both variants are ROHS3 compliant and carry improved moisture sensitivity ratings (MSL 2) compared to the original ICS853111AYLF (MSL 3), indicating better long-term storage and handling characteristics. The tighter supply voltage specification (2.375V to 3.8V) of the MC100LVEP111 series reflects modern low-voltage design practices while maintaining full compatibility with the original device's operating parameters.

Frequently Asked Questions (FAQ)

Q: Can MC100LVEP111 devices directly replace ICS853111AYLF in existing designs?

A: Yes. Both devices share identical 2:10 fanout buffer functionality, 3 GHz maximum frequency, 32-LQFP package, and -40°C to 85°C operating temperature range. The MC100LVEP111 input and output format support encompasses the formats supported by the ICS853111AYLF.

Q: What is the difference between MC100LVEP111FAG and MC100LVEP111FARG?

A: The primary difference is packaging format. MC100LVEP111FAG uses Tray packaging for lower-volume or manual assembly applications. MC100LVEP111FARG uses Tape & Reel (TR) format for automated high-volume assembly. Electrical specifications and performance are identical.

Q: Are there supply voltage compatibility concerns?

A: The MC100LVEP111 operates within 2.375V to 3.8V, which is a subset of the ICS853111AYLF range (2.375V to 5.25V). If your design requires operation above 3.8V, the MC100LVEP111 is not suitable. For designs operating at 3.8V or below, the MC100LVEP111 is fully compatible.

Q: What are the compliance and regulatory differences?

A: Both the ICS853111AYLF and MC100LVEP111 series carry REACH Unaffected and EAR99 ECCN classifications. The MC100LVEP111 series additionally provides ROHS3 compliance certification. Both share identical HTSUS classification (8542.39.0001).

Q: Does the improved moisture sensitivity rating (MSL 2 vs MSL 3) affect compatibility?

A: No. The lower MSL rating of the MC100LVEP111 (MSL 2, 1 Year) represents an improvement over the ICS853111AYLF (MSL 3, 168 Hours), indicating superior moisture resistance and longer shelf life. This does not affect electrical or functional compatibility.
