Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDCF2510PWR is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 24-TSSOP surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Supply Voltage: The substitute must operate within the 3V to 3.6V supply voltage range to function in systems designed for the CDCF2510PWR.

Operating Temperature Range: The substitute must support the 0°C to 85°C operating temperature specification.

PLL Functionality: The substitute must include integrated PLL functionality for clock generation and distribution.

Single Output Configuration: The substitute must provide a single output circuit to match the original design topology.

Compliance Standards: The substitute must maintain ROHS3 compliance and MSL Level 1 rating for environmental and handling requirements.

The CDCVF2510APWR meets all these substitution criteria while offering enhanced performance characteristics, including a higher maximum frequency rating of 175MHz and an improved input-to-output ratio of 2:11.

Parameter Comparison

Engineering Selection Recommendations

The CDCVF2510APWR is the primary substitute for the obsolete CDCF2510PWR. Both devices share identical package specifications, supply voltage requirements, operating temperature ranges, and compliance certifications. The substitute maintains full mechanical and electrical compatibility with existing CDCF2510PWR implementations.

The CDCVF2510APWR carries Active product status, ensuring long-term availability and manufacturing support. Both parts maintain ROHS3 compliance and MSL Level 1 ratings, meeting current environmental and handling standards.

The substitute offers enhanced performance with a maximum frequency rating of 175MHz compared to the original 140MHz specification, providing additional operational headroom for clock distribution applications. The CDCVF2510APWR also includes PLL bypass functionality, offering greater flexibility in system configuration.

Frequently Asked Questions (FAQ)

Q: Can the CDCVF2510APWR directly replace the CDCF2510PWR in existing designs?

A: Yes. Both devices use the identical 24-TSSOP package, operate within the same 3V to 3.6V supply voltage range, and support the 0°C to 85°C temperature specification. Pin-to-pin compatibility and functional equivalence are maintained.

Q: What is the difference in the input-to-output ratio between these parts?

A: The CDCF2510PWR provides a 1:10 ratio, while the CDCVF2510APWR provides a 2:11 ratio. Both ratios are suitable for DRAM DIMM clock distribution applications within their respective frequency specifications.

Q: Why is the CDCF2510PWR classified as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing and support for this device. The CDCVF2510APWR represents the current active alternative for equivalent clock driver functionality.

Q: Are there any compliance differences between the two parts?

A: No. Both the CDCF2510PWR and CDCVF2510APWR maintain ROHS3 compliance and MSL Level 1 ratings. Environmental and handling requirements are identical.

Q: What is the significance of the PLL bypass feature in the CDCVF2510APWR?

A: The PLL bypass capability in the substitute provides operational flexibility, allowing the device to function with or without PLL engagement depending on system requirements. This feature does not affect compatibility with designs using the original CDCF2510PWR.

Q: Are the packaging and mounting specifications identical?

A: Yes. Both parts use 24-TSSOP surface mount packages with identical physical dimensions (0.173", 4.40mm Width). PCB layout and reflow soldering processes require no modification.
