CDCVF2509PWR PLL Clock Driver Equivalent & Substitute Parts

Part Overview

The CDCVF2509PWR is a PLL Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and timing applications. This device operates at a maximum frequency of 175MHz with a 2:10 input-to-output ratio and supports LVTTL signal levels. The part is currently in Active product status with 1707 units available in stock.

Substitute parts may be required due to inventory constraints, design phase transitions, or application-specific frequency requirements. The following equivalent parts maintain core functional compatibility while offering alternative specifications or availability profiles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCVF2509PWR is determined by the following critical parameters:

Mandatory Compatibility Parameters:

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

Variable Parameters (Application-Dependent):

• Frequency - Max: 175MHz (primary specification) or lower
• Ratio - Input:Output: 2:10 (primary specification) or alternative ratios

The substitute parts listed below maintain all mandatory compatibility parameters. Variations in maximum frequency and input-to-output ratio reflect different product grades or design iterations within the same device family.

Engineering Selection Recommendations

CDCVF2509PWR (Primary Selection) This part is the recommended choice for new designs. Active product status ensures long-term availability and manufacturing support. It provides 175MHz maximum frequency with a 2:10 input-to-output ratio, meeting the full specification range for this device family.

CDC2509CPWR (Conditional Substitute) This part is suitable only for applications where the maximum frequency requirement is 125MHz or lower and the input-to-output ratio of 1:9 is functionally acceptable. The "Not For New Designs" status indicates this part is in transition and should not be selected for new development. Use only when existing inventory constraints or legacy system requirements necessitate substitution.

CDCVF2509APWR (Not Recommended) This part carries Obsolete product status and should not be selected for any new applications. While it maintains the 175MHz frequency and 2:10 ratio specifications, obsolete classification indicates discontinued manufacturing and limited future availability. Selection of this part introduces supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can CDC2509CPWR replace CDCVF2509PWR in all applications? A: No. CDC2509CPWR has a maximum frequency of 125MHz compared to 175MHz for CDCVF2509PWR, and a different input-to-output ratio of 1:9 versus 2:10. Substitution is valid only if your application operates at or below 125MHz and the 1:9 ratio meets functional requirements.

Q: Why is CDCVF2509APWR listed if it is obsolete? A: CDCVF2509APWR is included for reference purposes only, documenting the complete product family history. Obsolete status means manufacturing has been discontinued. This part should not be selected for new designs due to supply chain discontinuation risk.

Q: Are all three parts pin-compatible? A: Yes. All three parts use the identical 24-TSSOP package with 0.173" width and 4.40mm dimensions, ensuring mechanical and electrical pin compatibility at the package level. However, functional compatibility depends on frequency and ratio specifications matching application requirements.

Q: What is the significance of the "Not For New Designs" status on CDC2509CPWR? A: This status indicates the part is in end-of-life transition. While currently available in inventory (6632 units), Texas Instruments has designated it for legacy support only. New product designs should use CDCVF2509PWR instead.

Q: Are all substitute parts RoHS3 compliant? A: Yes. CDCVF2509PWR, CDC2509CPWR, and CDCVF2509APWR are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory requirements.

Q: What is the key difference between CDCVF2509PWR and CDCVF2509APWR? A: Both parts share identical electrical specifications (175MHz, 2:10 ratio, 3V-3.6V supply). The primary difference is product status: CDCVF2509PWR is Active, while CDCVF2509APWR is Obsolete. For new applications, CDCVF2509PWR is the only appropriate selection.
