ICS853111AV-01LFT Equivalent & Substitute Parts

Part Overview

The ICS853111AV-01LFT is a Clock Fanout Buffer (Distribution) IC manufactured by Renesas Electronics Corporation, designed for 1:9 clock distribution at frequencies up to 2 GHz. This part operates with differential LVDS/LVPECL inputs and ECL/LVPECL outputs, supporting supply voltages from 3V to 3.8V across the -40°C to 85°C operating temperature range. The device is packaged in a 28-LCC (J-Lead) surface mount configuration.

The ICS853111AV-01LFT is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support long-term product support for systems currently utilizing this clock distribution component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICS853111AV-01LFT is determined by the following critical parameters:

• 1:9 Input:Output Ratio: All substitute parts must maintain identical 1:9 fanout distribution
• Differential Input and Output: Substitutes must support differential signaling on both input and output
• Package Compatibility: All substitutes must use the 28-LCC (J-Lead) surface mount package
• Operating Temperature Range: Substitutes must support -40°C to 85°C operation
• Supply Voltage Compatibility: Substitutes must operate within or encompass the 3V to 3.8V supply range
• Signal Type Compatibility: Input and output signal types must be compatible with system requirements

The substitute parts identified fall into two performance categories based on maximum frequency specification:

Category 1 - Lower Frequency (650 MHz): CDCVF111FN and CDCVF111FNR from Texas Instruments. These parts support LVPECL input and output only, with reduced maximum frequency but active product status and superior compliance characteristics.

Category 2 - Mid-Range Frequency (1.5 GHz): MC100LVE111FNG and MC100LVE111FNR2G from onsemi. These parts support ECL and PECL input/output, operating at 1.5 GHz maximum frequency, with obsolete product status matching the original part.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Requirement:

If design specifications permit operation at 650 MHz maximum frequency, the Texas Instruments CDCVF111FN (tube packaging) or CDCVF111FNR (tape & reel packaging) are recommended. Both parts carry active product status, ROHS3 compliance, and superior moisture sensitivity characteristics (MSL 1 vs. MSL 3). These parts are suitable for new designs and long-term supply chain stability. Selection between tube and tape & reel packaging depends on assembly process requirements.

For Frequency Performance Matching:

If system design requires operation closer to 2 GHz maximum frequency, the onsemi MC100LVE111FNG (tube packaging) or MC100LVE111FNR2G (tape & reel packaging) provide 1.5 GHz maximum frequency operation. While these parts share obsolete product status with the original ICS853111AV-01LFT, they offer superior frequency performance compared to the Texas Instruments alternatives. These parts maintain identical supply voltage range (3V ~ 3.8V) and operating temperature specifications as the original part.

For Supply Voltage Compatibility:

The Texas Instruments CDCVF111 series operates at 3V ~ 3.6V, which is a subset of the original 3V ~ 3.8V range. System designs operating at supply voltages above 3.6V require the onsemi MC100LVE111 series (3V ~ 3.8V) or confirmation that the Texas Instruments parts function within the actual operating voltage of the application.

For Signal Type Compatibility:

The original ICS853111AV-01LFT accepts multiple input signal types (CML, LVDS, LVPECL, SSTL). The Texas Instruments CDCVF111 series accepts LVPECL input only. The onsemi MC100LVE111 series accepts ECL and PECL input. System designs utilizing CML, LVDS, or SSTL input signals require the onsemi MC100LVE111 series or signal conditioning to convert to compatible input types.

Frequently Asked Questions (FAQ)

Q: Can CDCVF111FN or CDCVF111FNR be used as direct replacements for ICS853111AV-01LFT?

A: Direct replacement is possible only if system design operates at clock frequencies of 650 MHz or below, uses LVPECL input signals, and operates within the 3V to 3.6V supply voltage range. If the original design requires 2 GHz operation, multiple input signal types, or supply voltages above 3.6V, these parts are not suitable direct replacements.

Q: What is the difference between CDCVF111FN and CDCVF111FNR?

A: Both parts are identical in electrical specifications and performance. The difference is packaging format: CDCVF111FN is supplied in tube packaging, while CDCVF111FNR is supplied in tape & reel (TR) format. Selection depends on assembly process requirements and volume handling procedures.

Q: Why do the onsemi MC100LVE111 parts have obsolete status like the original part?

A: Both the original Renesas ICS853111AV-01LFT and the onsemi MC100LVE111 series are classified as obsolete products. However, the onsemi parts currently maintain higher inventory levels (1293 and 2105 pieces respectively) compared to the original part (740 pieces), providing near-term supply availability despite obsolete classification.

Q: Are the Texas Instruments CDCVF111 parts suitable for new product designs?

A: Yes. The Texas Instruments CDCVF111 series carries active product status, ROHS3 compliance, and superior moisture sensitivity characteristics (MSL 1 vs. MSL 3). These parts are appropriate for new designs where the 650 MHz frequency specification meets system requirements and LVPECL signal compatibility is available.

Q: What is the impact of MSL (Moisture Sensitivity Level) differences?

A: The original ICS853111AV-01LFT and onsemi MC100LVE111 series are rated MSL 3 (168 hours), requiring controlled storage and handling procedures. The Texas Instruments CDCVF111 series is rated MSL 1 (unlimited), eliminating moisture sensitivity constraints. MSL 1 parts offer simplified inventory management and reduced risk of moisture-related failures during storage and assembly.

Q: Can I use MC100LVE111FNG and MC100LVE111FNR2G interchangeably?

A: Yes. Both parts are electrically identical. MC100LVE111FNG is supplied in tube packaging, while MC100LVE111FNR2G is supplied in tape & reel format. Selection depends on assembly process and volume handling requirements.

Q: What happens if my system operates at supply voltages between 3.6V and 3.8V?

A: The Texas Instruments CDCVF111 series is specified only to 3.6V maximum supply voltage. If your system requires operation at 3.7V or 3.8V, use the onsemi MC100LVE111 series (rated 3V ~ 3.8V) or the original Renesas ICS853111AV-01LFT. Operating the CDCVF111 above its specified maximum voltage is not recommended.
