CSP2510DPG8 Equivalent & Substitute Parts

Part Overview

The CSP2510DPG8 is a PLL Clock Driver IC manufactured by Renesas Electronics Corporation, designed for clock distribution and zero delay buffering applications. This device features a 1:10 input-to-output ratio with a maximum frequency of 175MHz and operates from a 3V to 3.6V supply. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Texas Instruments offers compatible alternatives that maintain functional equivalence while providing improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSP2510DPG8 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Package / Case: 24-TSSOP (0.173", 4.40mm Width) — mandatory for PCB compatibility
• Voltage - Supply: 3V ~ 3.6V — required for circuit operation
• Operating Temperature: 0°C ~ 85°C — functional range requirement
• PLL with Bypass: Yes — functional architecture requirement
• Number of Circuits: 1 — circuit count requirement
• Mounting Type: Surface Mount — assembly compatibility

Secondary Compatibility Parameters:

• Input / Output signal type and frequency capability
• Input:Output ratio configuration
• Differential signal support (No/No for this application)

The substitute parts are grouped into two functional categories based on frequency and ratio specifications:

Group A (CDC2510 Series): Texas Instruments CDC2510CPW, CDC2510CPWG4, and CDC2510CPWR operate at 125MHz maximum frequency with 1:10 input-to-output ratio, matching the core functional specification of the CSP2510DPG8.

Group B (CDCVF2510 Series): Texas Instruments CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, and CDCVF2510PWR operate at 175MHz maximum frequency with 2:11 input-to-output ratio, providing higher frequency capability while maintaining the same package and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring exact frequency and ratio match (175MHz, 1:10): The CSP2510DPG8 has no direct functional equivalent among the listed substitutes. The device combines 175MHz maximum frequency with a 1:10 input-to-output ratio, a specification unique to the Renesas part. No Texas Instruments substitute maintains both parameters simultaneously.

For applications tolerant of 125MHz operation (1:10 ratio): The CDC2510 series (CDC2510CPW, CDC2510CPWG4, CDC2510CPWR) provides functional substitution with reduced maximum frequency. These parts maintain the 1:10 ratio and identical package, voltage, and temperature specifications. All CDC2510 variants are ROHS3 compliant with MSL 1 rating, offering superior compliance and moisture handling compared to the obsolete CSP2510DPG8.

For applications requiring 175MHz operation with alternative ratio (2:11): The CDCVF2510 series (CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR) operates at 175MHz with a 2:11 input-to-output ratio. These parts are currently active products with ROHS3 compliance and MSL 1 rating. Selection within this series depends on packaging requirements: tube packaging (APW, PW) or tape & reel (APWR, PWR).

Compliance Considerations: All Texas Instruments substitutes are ROHS3 compliant, addressing the RoHS non-compliance status of the CSP2510DPG8. All substitutes feature MSL 1 (unlimited moisture sensitivity), improving handling and storage requirements compared to the MSL 3 rating of the original part.

Frequently Asked Questions (FAQ)

Q: Can CDC2510 parts directly replace CSP2510DPG8 in existing designs? A: CDC2510 parts are mechanically and electrically compatible at the package and supply voltage level. However, the maximum frequency is reduced from 175MHz to 125MHz. Substitution is valid only if the application operates at or below 125MHz and the 1:10 ratio requirement is maintained.

Q: What is the difference between CDCVF2510APW and CDCVF2510APWR? A: Both parts are functionally identical with 175MHz maximum frequency and 2:11 input-to-output ratio. The difference is packaging: APW is supplied in tube packaging, while APWR is supplied in tape & reel format. Selection depends on assembly process requirements and quantity needs.

Q: Why do CDCVF2510 parts have a different input-to-output ratio (2:11 vs. 1:10)? A: The CDCVF2510 series is a different product line within Texas Instruments' clock driver portfolio. While it maintains the same package, supply voltage, and operating temperature as the CSP2510DPG8, the internal PLL configuration differs, resulting in a 2:11 ratio instead of 1:10. This ratio difference must be evaluated against application requirements.

Q: Are all substitute parts currently available? A: The CDCVF2510 series (APW, APWR, PW, PWR) are active products with substantial inventory. The CDC2510 series are marked "Not For New Designs" or "Discontinued at DiGi Electronics," indicating limited availability for new applications. For new designs, CDCVF2510 variants are the recommended choice.

Q: What is the MSL difference and why does it matter? A: The CSP2510DPG8 has MSL 3 (168-hour moisture sensitivity limit), while all Texas Instruments substitutes have MSL 1 (unlimited). MSL 1 parts can be stored indefinitely without moisture baking requirements, reducing handling complexity and cost in manufacturing environments.

Q: Can I use CDCVF2510 parts if my design requires a 1:10 ratio? A: No. The CDCVF2510 series operates with a 2:11 ratio, which is not equivalent to 1:10. If your application specifically requires 1:10 ratio operation, only CDC2510 parts provide this specification among the listed substitutes. Frequency requirements must then be evaluated against the 125MHz maximum of CDC2510.
