VF2510BGLF PLL Clock Driver Equivalent & Substitute Parts

Part Overview

The VF2510BGLF is a PLL clock driver IC manufactured by Renesas Electronics Corporation, designed for memory and SDRAM DIMM applications. This 24-TSSOP surface mount device operates at 3.3V and provides clock buffering and driving functionality with a 1:10 input-to-output ratio at frequencies up to 200MHz. The part is currently obsolete, making equivalent substitutes from active manufacturers necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the VF2510BGLF is based on the following critical parameters:

• Package compatibility: 24-TSSOP form factor with identical 0.173" width and 4.40mm dimensions
• Functional equivalence: PLL clock driver with single output circuit
• Supply voltage overlap: Operating range must accommodate 3.3V nominal operation
• Frequency capability: Maximum frequency rating must support 200MHz operation
• Mounting type: Surface mount technology compatibility
• Moisture sensitivity: MSL rating of 1 or better

The Texas Instruments CDCVF2510 series parts (CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR) meet these substitution criteria. While these parts feature a 2:11 input-to-output ratio and maximum frequency of 175MHz (lower than the original), they operate within the required 3V to 3.6V supply range and maintain identical packaging and mounting specifications. The difference in ratio and frequency represents a functional trade-off acceptable for applications where the lower specifications are sufficient.

Parameter Comparison

Engineering Selection Recommendations

The CDCVF2510 series from Texas Instruments provides active production alternatives to the obsolete VF2510BGLF. All four substitute part numbers (CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR) are functionally equivalent within the constraints of their specified parameters and offer the following advantages:

• Active product status: Ensures long-term availability and supply chain stability
• ROHS3 compliance: Meets current environmental and regulatory requirements
• Extended operating temperature range: 0°C to 85°C versus the original 0°C to 70°C
• Identical packaging: Direct PCB layout compatibility with 24-TSSOP footprint
• Supply voltage compatibility: 3V to 3.6V range encompasses standard 3.3V operation

Selection between the four substitute options depends on packaging preference: CDCVF2510APW and CDCVF2510PW are supplied in Tube packaging, while CDCVF2510APWR and CDCVF2510PWR are supplied in Tape & Reel format. The choice between these variants should be based on procurement volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can CDCVF2510 series parts directly replace VF2510BGLF without circuit modifications?

A: The CDCVF2510 series maintains identical 24-TSSOP packaging and pinout compatibility. However, the input-to-output ratio differs (2:11 versus 1:10) and maximum frequency is lower (175MHz versus 200MHz). Circuit validation is required to confirm the lower frequency specification and different ratio are acceptable for your specific application.

Q: What is the difference between CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, and CDCVF2510PWR?

A: These part numbers represent the same IC with different packaging formats. CDCVF2510APW and CDCVF2510PW are supplied in Tube packaging for lower-volume applications. CDCVF2510APWR and CDCVF2510PWR are supplied in Tape & Reel format for automated assembly and higher-volume production. The "APW" and "PW" designations indicate packaging type; the "R" suffix in APWR and PWR indicates Tape & Reel format.

Q: Are the CDCVF2510 parts compatible with 3.3V supply voltage?

A: Yes. The CDCVF2510 series operates within a 3V to 3.6V supply range, which encompasses standard 3.3V operation. This overlaps with the VF2510BGLF supply range of 2.97V to 3.63V.

Q: What is the significance of the "PLL with Bypass" feature in the CDCVF2510 series?

A: The CDCVF2510 series includes bypass capability in addition to PLL functionality, providing operational flexibility. The original VF2510BGLF features PLL only. This additional capability does not prevent substitution but may require firmware or configuration adjustments depending on your system design.

Q: Do all CDCVF2510 variants have the same electrical specifications?

A: Yes. CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, and CDCVF2510PWR share identical electrical specifications, frequency ratings, voltage requirements, and operating temperature ranges. Differences are limited to packaging format and supplier delivery method.

Q: Is the extended operating temperature range (0°C to 85°C) of the CDCVF2510 a concern for applications designed for 0°C to 70°C?

A: No. The extended temperature range of the CDCVF2510 series is a superset of the original VF2510BGLF specification. Parts rated for wider temperature ranges maintain specifications across the narrower original range, making them suitable for existing applications.
