Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the ICS853111AV-01LF is determined by the following critical parameters:

Primary Substitution Criteria:

• Ratio - Input:Output: 1:9 (exact match required)
• Differential - Input:Output: Yes/Yes (exact match required)
• Package / Case: 28-LCC (J-Lead) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

Secondary Compatibility Factors:

• Frequency - Max: Must equal or exceed 2 GHz for full functional equivalence
• Voltage - Supply: Must overlap with 3V ~ 3.8V range
• Input/Output Standards: Must support LVPECL for core compatibility

The substitute parts identified below meet the primary substitution criteria. Frequency derating applies to parts with maximum frequency below 2 GHz, which may limit operation in high-frequency applications.

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments CDCVF111 Series (CDCVF111FN / CDCVF111FNR): These parts represent the primary active substitute option. Both variants meet all primary substitution criteria with identical electrical specifications. The CDCVF111FN is supplied in Tube packaging, while CDCVF111FNR is supplied in Tape & Reel format for automated assembly. Both achieve ROHS3 compliance and feature superior moisture sensitivity rating (MSL 1 vs. MSL 3). Frequency limitation to 650 MHz requires application verification for systems designed to operate at the full 2 GHz capability of the original part.

onsemi MC100LVE111 Series (MC100LVE111FNG / MC100LVE111FNR2G): These parts provide intermediate frequency performance at 1.5 GHz, bridging the gap between the Texas Instruments 650 MHz option and the original 2 GHz specification. Both variants maintain voltage supply compatibility with the original part and identical operating temperature range. Product status is Obsolete for both variants. The MC100LVE111FNG is supplied in Tube packaging, while MC100LVE111FNR2G is supplied in Tape & Reel format.

Compliance and Certification: All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification consistent with the original part. Texas Instruments variants provide enhanced RoHS3 compliance and improved moisture handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can CDCVF111FN or CDCVF111FNR directly replace ICS853111AV-01LF in existing designs?

A: Mechanical and electrical interface compatibility is confirmed through matching 1:9 ratio, differential input/output configuration, 28-LCC package, and operating temperature range. However, the 650 MHz maximum frequency represents a significant derating from the original 2 GHz specification. Substitution is valid only for applications operating at or below 650 MHz. Systems requiring full 2 GHz performance must use MC100LVE111 variants or identify alternative solutions.

Q: What is the difference between Tube and Tape & Reel packaging options?

A: Tube packaging (CDCVF111FN, MC100LVE111FNG) is suitable for manual assembly and lower-volume applications. Tape & Reel packaging (CDCVF111FNR, MC100LVE111FNR2G) is optimized for automated pick-and-place assembly in high-volume production. Electrical performance is identical between packaging variants of the same base part number.

Q: Why do the Texas Instruments parts have lower maximum frequency than the original?

A: The CDCVF111 series is designed for 650 MHz operation, which is a different product tier within the clock distribution IC market. This represents a trade-off in the product design. Applications limited to 650 MHz or below can utilize these parts without performance compromise.

Q: Are the onsemi MC100LVE111 variants still available for new designs?

A: Both MC100LVE111FNG and MC100LVE111FNR2G are classified as Obsolete. While inventory is currently available, these parts are not recommended for new design implementations. The Texas Instruments CDCVF111 series (Active status) is the preferred substitute for long-term product support.

Q: What is the significance of MSL rating differences?

A: The original ICS853111AV-01LF carries MSL 3 (168 Hours), requiring controlled moisture exposure during storage and handling. Texas Instruments CDCVF111 variants feature MSL 1 (Unlimited), eliminating moisture sensitivity constraints. This represents an improvement in supply chain handling and storage flexibility.

Q: Do input standard differences affect substitution compatibility?

A: The original part supports CML, LVDS, LVPECL, and SSTL inputs with ECL and LVPECL outputs. Texas Instruments CDCVF111 variants support LVPECL input and output only. onsemi MC100LVE111 variants support ECL and PECL input and output. Substitution requires verification that the system input signal standard is supported by the selected replacement part.
