Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICS853011CMLF are qualified based on the following critical parameters that determine functional compatibility:

Core Substitution Criteria:

• Ratio - Input:Output: 1:2 (mandatory match)
• Differential - Input:Output: Yes/Yes (mandatory match)
• Package / Case: 8-SOIC (0.154", 3.90mm Width) (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Operating Temperature: -40°C ~ 85°C (mandatory match)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (mandatory match)

Performance Considerations:

• Frequency - Max: Substitute parts rated at 3 GHz exceed the 2.5 GHz requirement and are compatible
• Voltage - Supply: Substitute parts with 2.375V ~ 3.8V or wider ranges (2.375V ~ 5.5V) are compatible
• Input/Output Standards: Substitute parts must support at least the input and output standards required by the application

Substitute parts are grouped into two categories: Renesas Electronics Corporation parametric equivalents and manufacturer-recommended alternatives from onsemi and Microchip Technology.

Parameter Comparison

Engineering Selection Recommendations

Renesas Electronics Corporation Parametric Equivalent:

The 853S011BMILF is a direct parametric equivalent to the ICS853011CMLF, manufactured by Renesas Electronics Corporation. This part maintains identical electrical specifications including 2.5 GHz maximum frequency, 2.375V ~ 3.8V supply voltage range, and 1:2 differential fanout capability. The 853S011BMILF is classified as Active product status and is ROHS3 compliant, making it the preferred choice for direct replacement in existing designs. Packaging is available in Tube format.

onsemi Manufacturer-Recommended Alternatives:

The MC100LVEP11DR2G and MC10LVEP11DR2G are onsemi alternatives that exceed the frequency specification at 3 GHz while maintaining all other critical parameters. Both parts are Active status and ROHS3 compliant. The MC100LVEP11DR2G is available in Tape & Reel (TR) packaging with 30,300 units in stock. The MC10LVEP11DR2G is available in Cut Tape (CT) & Digi-Reel® packaging with 17,880 units in stock. These parts support CML, LVDS, and PECL input standards with ECL and PECL output capability.

Microchip Technology Manufacturer-Recommended Alternatives:

The SY100EP11UZG-TR and SY10EP11UZG-TR are Microchip Technology alternatives rated at 3 GHz maximum frequency. Both parts are Active status and ROHS3 compliant. The SY100EP11UZG-TR supports ECL, LVECL, LVPECL, and PECL input/output standards with supply voltage range of 2.375V ~ 5.5V. The SY10EP11UZG-TR is optimized for LVECL and LVPECL standards with the same supply voltage range. Both parts are available in Tape & Reel (TR) packaging.

Frequently Asked Questions (FAQ)

Q: Can the ICS853011CMLF be directly replaced with the 853S011BMILF?

A: Yes. The 853S011BMILF is a parametric equivalent manufactured by Renesas Electronics Corporation with identical electrical specifications, package type, and operating parameters. The primary difference is product status: the 853S011BMILF is Active while the ICS853011CMLF is Obsolete.

Q: What is the primary advantage of onsemi and Microchip alternatives over the Renesas 853S011BMILF?

A: The onsemi MC100LVEP11DR2G, MC10LVEP11DR2G and Microchip SY100EP11UZG-TR, SY10EP11UZG-TR are rated at 3 GHz maximum frequency, exceeding the 2.5 GHz specification of the original part. This provides additional performance margin for high-speed clock distribution applications. All alternatives maintain the 1:2 differential fanout ratio and 8-SOIC package requirement.

Q: Are there differences in input/output signal standards between substitute parts?

A: Yes. The original ICS853011CMLF supports CML, LVDS, LVPECL, and SSTL inputs with ECL and LVPECL outputs. The onsemi alternatives (MC100LVEP11DR2G, MC10LVEP11DR2G) support CML, LVDS, and PECL inputs with ECL and PECL outputs. The Microchip SY100EP11UZG-TR supports ECL, LVECL, LVPECL, and PECL standards. The Microchip SY10EP11UZG-TR is optimized for LVECL and LVPECL standards. Verify that the selected substitute supports the specific signal standards required by your application.

Q: What is the difference between MC100LVEP11DR2G and MC10LVEP11DR2G?

A: Both parts are onsemi 1:2 fanout buffers rated at 3 GHz with identical electrical specifications. The primary differences are packaging format (MC100LVEP11DR2G is Tape & Reel with 30,300 units in stock; MC10LVEP11DR2G is Cut Tape & Digi-Reel® with 17,880 units in stock) and availability. Select based on your procurement and assembly requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (853S011BMILF, MC100LVEP11DR2G, MC10LVEP11DR2G, SY100EP11UZG-TR, SY10EP11UZG-TR) are ROHS3 compliant. The original ICS853011CMLF RoHS status is not specified in the provided data.

Q: Can I use a substitute part rated at 3 GHz in an application designed for 2.5 GHz?

A: Yes. A 3 GHz rated part exceeds the 2.5 GHz requirement and is compatible with applications designed for the lower frequency. The part will operate within specification at 2.5 GHz and below.

Q: What supply voltage range should I verify for my application?

A: The original ICS853011CMLF operates at 2.375V ~ 3.8V. The Renesas 853S011BMILF maintains this range. The onsemi alternatives (MC100LVEP11DR2G, MC10LVEP11DR2G) also operate at 2.375V ~ 3.8V. The Microchip alternatives (SY100EP11UZG-TR, SY10EP11UZG-TR) support a wider range of 2.375V ~ 5.5V. Verify that your power supply design matches the selected substitute part's voltage requirements.
