CSP2510DPG Equivalent & Substitute Parts

Part Overview

The CSP2510DPG 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 packaged in a 24-TSSOP surface mount package.

The CSP2510DPG is classified as obsolete. Due to its discontinued status and limited availability for new production, equivalent substitute parts from Texas Instruments are necessary for ongoing design support and production continuity.

Supply voltage range: 3V ~ 3.6V
Operating temperature: 0°C ~ 85°C
PLL with bypass functionality
Single circuit configuration
Surface mount mounting type

Substitution Groups:

Group 1: Direct Functional Equivalents (1:10 Ratio, 125MHz) CDC2510CPW, CDC2510CPWG4, and CDC2510CPWR are Texas Instruments PLL Clock Drivers with identical 1:10 input-to-output ratio and matching package specifications. These parts operate at 125MHz maximum frequency, which is within the operational envelope for applications designed for the CSP2510DPG. All three variants share the same base product number CDC2510 and are electrically interchangeable.

Group 2: Enhanced Performance Equivalents (2:11 Ratio, 175MHz) CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, and CDCVF2510PWR are Texas Instruments PLL Clock Drivers with 175MHz maximum frequency matching the CSP2510DPG. These parts feature a 2:11 input-to-output ratio and LVTTL input/output signaling. The higher frequency capability and different ratio require circuit-level evaluation for compatibility with existing designs.

Engineering Selection Recommendations

For Existing Designs Requiring Direct Replacement:

The CDC2510 series (CDC2510CPW, CDC2510CPWG4, CDC2510CPWR) provides the closest functional match with identical 1:10 input-to-output ratio. These parts are classified as "Not For New Designs" or "Discontinued at DiGi Electronics," indicating limited long-term availability. All CDC2510 variants are ROHS3 compliant with MSL rating of 1 (Unlimited), representing improved environmental and moisture handling compared to the original CSP2510DPG.

For New Designs or Long-Term Production:

The CDCVF2510 series (CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR) is classified as Active and offers the best long-term availability. These parts match the 175MHz maximum frequency of the CSP2510DPG and feature LVTTL input/output signaling. The 2:11 input-to-output ratio differs from the original 1:10 ratio and requires circuit-level evaluation. All CDCVF2510 variants are ROHS3 compliant with MSL rating of 1 (Unlimited).

Packaging Considerations:

All substitute parts are available in 24-TSSOP surface mount packages with identical physical dimensions. Packaging variants (Tube, Tape & Reel) do not affect electrical compatibility. CDC2510CPWR and CDCVF2510APWR, CDCVF2510PWR offer the highest inventory levels for production quantities.

Frequently Asked Questions (FAQ)

Q: Can CDC2510CPW directly replace CSP2510DPG without circuit modification?

A: CDC2510CPW shares the same 1:10 input-to-output ratio, supply voltage range, operating temperature, and 24-TSSOP package as the CSP2510DPG. The maximum frequency is 125MHz versus 175MHz for the original part. Direct replacement is possible if the application operates below 125MHz. Verify input/output signal compatibility with your circuit design.

Q: What is the difference between CDC2510 and CDCVF2510 series?

A: The CDC2510 series maintains the 1:10 input-to-output ratio with 125MHz maximum frequency. The CDCVF2510 series operates at 175MHz with a 2:11 input-to-output ratio and LVTTL signaling. The different ratio requires circuit-level evaluation to confirm compatibility with existing clock distribution networks.

Q: Are all substitute parts RoHS compliant?

A: All Texas Instruments substitute parts (CDC2510 and CDCVF2510 series) are ROHS3 compliant. The original CSP2510DPG is RoHS non-compliant. This represents an improvement in environmental compliance for new production.

Q: What is the MSL rating difference, and does it matter?

A: The CSP2510DPG has MSL rating 3 (168 hours), while all Texas Instruments substitutes have MSL rating 1 (Unlimited). MSL rating 1 indicates superior moisture resistance and longer shelf life without baking requirements. This is advantageous for inventory management and production scheduling.

Q: Which substitute part has the best availability?

A: CDCVF2510PWR and CDC2510CPWR show the highest inventory levels (17,883 and 16,546 units respectively). CDCVF2510PWR is classified as Active, ensuring continued availability for future production. CDC2510CPWR is classified as "Not For New Designs," indicating potential future discontinuation.

Q: Can I use CDCVF2510 in place of CDC2510?

A: Both series share identical package, supply voltage, and operating temperature specifications. The CDCVF2510 series offers higher frequency capability (175MHz) and LVTTL signaling. The 2:11 ratio versus 1:10 ratio requires circuit-level analysis to confirm timing compatibility with your clock distribution architecture.

Q: What packaging options are available?

A: Substitute parts are available in Tube packaging (CDC2510CPW, CDCVF2510APW, CDCVF2510PW) and Tape & Reel packaging (CDC2510CPWR, CDCVF2510APWR, CDCVF2510PWR). Packaging format does not affect electrical performance; selection depends on production volume and handling requirements.
