CDCVF2510PWG4 Equivalent & Substitute Parts

Part Overview

The CDCVF2510PWG4 is a PLL Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and timing applications requiring up to 175MHz frequency operation. This device features a 2:11 input-to-output ratio with LVTTL signal compatibility and operates across a 3V to 3.6V supply range in a 24-TSSOP surface mount package.

The CDCVF2510PWG4 is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement. Substitute parts must maintain compatibility with the original electrical specifications, package form factor, and operating parameters to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution eligibility for the CDCVF2510PWG4 is determined by the following critical parameters:

Primary Compatibility Criteria:

Package / Case: 24-TSSOP (0.173", 4.40mm Width)
Voltage - Supply: 3V ~ 3.6V
Operating Temperature: 0°C ~ 85°C
Input Signal Type: LVTTL
Output Signal Type: LVTTL
Mounting Type: Surface Mount

Secondary Compatibility Criteria:

Frequency - Max: 175MHz or higher
Ratio - Input:Output: 2:11 (exact match preferred for direct substitution)
PLL with Bypass capability

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Ratio): Parts maintaining the 2:11 input-to-output ratio provide pin-for-pin compatibility and require no circuit redesign.

Parametric Equivalents (Different Ratio): Parts with alternative input-to-output ratios (2:10 or 1:9) maintain electrical and mechanical compatibility but may require circuit-level evaluation for frequency scaling applications.

Engineering Selection Recommendations

Recommended Primary Substitute: CDCVF2510PW

The CDCVF2510PW is the preferred direct replacement for the CDCVF2510PWG4. This part maintains identical electrical specifications (2:11 ratio, 175MHz maximum frequency) and mechanical compatibility (24-TSSOP package). The CDCVF2510PW carries Active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory compliance for new designs.

Alternative Direct Equivalent: CDCVF2510APW

The CDCVF2510APW provides equivalent functionality with identical ratio and frequency specifications. This part is also Active status with full compliance certifications. Selection between CDCVF2510PW and CDCVF2510APW may be determined by packaging preference (Tube) and inventory availability.

Secondary Substitute: CDCVF2509PW

The CDCVF2509PW is a parametric equivalent with a 2:10 input-to-output ratio and 175MHz maximum frequency. This part maintains all electrical and mechanical compatibility parameters but requires circuit-level verification for applications dependent on the specific 2:11 frequency multiplication ratio. The CDCVF2509PW carries Active product status.

Not Recommended for New Designs:

The CDCVF2509APW (Obsolete status) and CDC2509CPW (Not For New Designs status, 125MHz maximum frequency) are not suitable for new design implementations. These parts present long-term supply and support risks.

Frequently Asked Questions (FAQ)

Q: Can CDCVF2510PW directly replace CDCVF2510PWG4 without circuit modification?

A: Yes. The CDCVF2510PW maintains identical electrical specifications (2:11 ratio, 175MHz frequency, LVTTL input/output, 3V-3.6V supply) and package form factor (24-TSSOP). Direct substitution is supported without circuit redesign.

Q: What is the difference between CDCVF2510PW and CDCVF2510APW?

A: Both parts are functionally identical with 2:11 ratio and 175MHz specifications. The difference lies in manufacturing date code and packaging designation. Both are Active status with equivalent compliance certifications.

Q: Can CDCVF2509PW be used as a substitute?

A: The CDCVF2509PW is mechanically and electrically compatible but features a 2:10 input-to-output ratio instead of 2:11. Applications requiring precise frequency multiplication must evaluate whether the different ratio affects system performance. The 175MHz maximum frequency remains unchanged.

Q: Why is CDC2509CPW not recommended?

A: The CDC2509CPW carries "Not For New Designs" product status and operates at a maximum frequency of 125MHz, which is lower than the original 175MHz specification. This part presents obsolescence risk and reduced frequency capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (CDCVF2510PW, CDCVF2510APW, CDCVF2509PW, CDCVF2509APW, and CDC2509CPW) maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in Tube packaging. The original CDCVF2510PWG4 packaging designation is not specified in available data. Tube packaging is standard for surface mount clock driver ICs and is compatible with automated assembly processes.
