CDCLVP110VFR Equivalent & Substitute Parts

Part Overview

The CDCLVP110VFR is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Texas Instruments, designed for high-speed clock distribution applications. This 2:10 configuration device operates at frequencies up to 4.6 GHz and is housed in a 32-LQFP surface mount package. The part is currently active in production with 2482 units in stock. Alternative models become necessary when the primary part is unavailable, when different packaging requirements exist, or when equivalent performance from alternative manufacturers is required for supply chain flexibility.

Substitute Part Grouping Explanation

Substitution for the CDCLVP110VFR is determined by the following critical parameters: 2:10 input-to-output ratio, maximum frequency capability of 3.0 GHz or higher, supply voltage range of 2.375V to 3.8V, operating temperature range of -40°C to 85°C, surface mount package format, and compatibility with HSTL and LVPECL input/output standards.

Substitute parts are grouped into two categories:

Parametric Equivalents (Texas Instruments): CDCLVP110MVFR and CDCLVP110VFRG4 are direct parametric equivalents from the same manufacturer, sharing identical electrical specifications and the same base product number CDCLVP110. These differ only in packaging designation or product status.

Direct Manufacturer Alternatives: M100LVEP111FATWG, MC100LVEP111FARG (onsemi), and SY100EP111UTG-TR (Microchip Technology) are functionally equivalent parts from alternative manufacturers. These maintain the 2:10 ratio, support the required voltage and temperature ranges, and operate at 3.0 GHz maximum frequency. Package variations exist: onsemi parts use 32-LQFP, while the Microchip part uses 32-TQFP.

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer): CDCLVP110MVFR is the preferred parametric equivalent, offering identical electrical performance to the CDCLVP110VFR with higher inventory availability (3400 units). Both parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating. CDCLVP110VFRG4 shares identical specifications but carries discontinued status at DiGi Electronics and should be avoided for new designs.

For Cross-Manufacturer Substitution: MC100LVEP111FARG (onsemi) is the most readily available alternative with 31195 units in stock and maintains full parametric compatibility within the 3.0 GHz maximum frequency specification. This part is ROHS3 compliant and REACH unaffected. The 32-LQFP package matches the original part, eliminating PCB layout modifications.

For Alternative Package Consideration: SY100EP111UTG-TR (Microchip Technology) provides equivalent functionality in a 32-TQFP package. This substitution requires PCB footprint verification due to package geometry differences between LQFP and TQFP formats, though both maintain 7x7mm dimensions. This part carries MSL 1 (Unlimited) rating and is ROHS3 compliant.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can CDCLVP110MVFR be used as a direct drop-in replacement for CDCLVP110VFR?

A: Yes. CDCLVP110MVFR is a parametric equivalent with identical electrical specifications, package format (32-LQFP), and compliance certifications. No circuit modifications are required.

Q: What is the frequency difference between the Texas Instruments CDCLVP110VFR (4.6 GHz) and onsemi alternatives (3.0 GHz)?

A: The CDCLVP110VFR supports operation up to 4.6 GHz, while M100LVEP111FATWG and MC100LVEP111FARG support up to 3.0 GHz. For applications operating below 3.0 GHz, onsemi parts are fully compatible. Applications requiring operation above 3.0 GHz must use the Texas Instruments part or verify that the onsemi part meets specific frequency requirements.

Q: Are there package differences between substitute parts?

A: CDCLVP110VFR, CDCLVP110MVFR, M100LVEP111FATWG, and MC100LVEP111FARG all use 32-LQFP packages. SY100EP111UTG-TR uses 32-TQFP, which has different pin geometry. Verify PCB footprint compatibility before selecting the Microchip part.

Q: What is the difference between LVPECL and LVECL output standards?

A: Both are low-voltage differential signaling standards. LVPECL (Low-Voltage Positive ECL) and LVECL (Low-Voltage ECL) are compatible in most applications. Verify specific signal level requirements in your circuit design before substitution.

Q: Which substitute part has the best inventory availability?

A: MC100LVEP111FARG (onsemi) has the highest inventory with 31195 units in stock, followed by CDCLVP110MVFR (Texas Instruments) with 3400 units.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original CDCLVP110VFR.
