CDCVF2509APW PLL Clock Driver IC Equivalent & Substitute Parts

Part Overview

The CDCVF2509APW is a PLL Clock Driver IC manufactured by Texas Instruments, designed for clock distribution and timing applications. This device features a 175MHz maximum frequency with a 2:10 input-to-output ratio and operates on a 3V to 3.6V supply. The part is classified as Obsolete, making identification of suitable substitutes essential for ongoing system support and new design considerations. Equivalent parts must maintain compatibility across electrical specifications, package configuration, and functional performance parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the CDCVF2509APW is determined by strict adherence to the following critical parameters:

Mandatory Compatibility Criteria:

Package Type: 24-TSSOP (0.173", 4.40mm Width) — physical and electrical pin compatibility required
Voltage Supply Range: 3V ~ 3.6V — must operate within specified supply window
Input/Output Signal Type: LVTTL — logic level compatibility essential
Operating Temperature Range: 0°C ~ 85°C — thermal operating envelope
Number of Circuits: 1 — single circuit configuration
PLL with Bypass functionality — required feature set

Allowable Variation Parameters:

Frequency - Max: Substitutes may operate at different maximum frequencies provided the application requirement does not exceed the substitute's rated frequency
Input:Output Ratio: Substitutes may have different ratios (1:9 vs 2:10) if the application timing requirements are met

Two substitute parts meet these criteria and are grouped accordingly based on their frequency and ratio specifications.

Engineering Selection Recommendations

CDCVF2509PW is the primary substitute for CDCVF2509APW. Both parts share identical electrical specifications: 175MHz maximum frequency, 2:10 input-to-output ratio, LVTTL signal compatibility, and 3V to 3.6V supply voltage. CDCVF2509PW holds Active product status, ensuring continued availability and manufacturing support. This part is suitable for both replacement applications and new designs requiring equivalent performance characteristics.

CDC2509CPW is a secondary substitute applicable only when application timing requirements do not exceed 125MHz. This part operates at a reduced maximum frequency and features a 1:9 input-to-output ratio, differing from the main part's 2:10 ratio. CDC2509CPW carries Not For New Designs status, limiting its use to legacy system maintenance where frequency and ratio specifications align with application requirements.

Both substitutes maintain full compliance with ROHS3 and REACH requirements, identical MSL ratings, and compatible 24-TSSOP packaging for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can CDCVF2509PW directly replace CDCVF2509APW in existing designs?

A: Yes. CDCVF2509PW provides identical electrical performance with matching 175MHz frequency, 2:10 ratio, LVTTL signal types, and 3V to 3.6V supply specifications. The 24-TSSOP package ensures pin-compatible board-level substitution. CDCVF2509PW's Active status makes it the recommended choice for ongoing production.

Q: What are the limitations of CDC2509CPW as a substitute?

A: CDC2509CPW operates at a maximum frequency of 125MHz compared to the main part's 175MHz, and features a 1:9 input-to-output ratio instead of 2:10. Substitution is valid only when the application's clock frequency requirement does not exceed 125MHz and the timing ratio is compatible with 1:9 multiplication. CDC2509CPW's Not For New Designs status restricts its use to legacy system support.

Q: Are package dimensions identical across all three parts?

A: Yes. CDCVF2509APW, CDC2509CPW, and CDCVF2509PW all use the 24-TSSOP package with 0.173" width and 4.40mm body width. Pin configuration and footprint are identical, enabling direct PCB-level replacement without layout modifications.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. CDCVF2509APW, CDC2509CPW, and CDCVF2509PW are all ROHS3 Compliant, REACH Unaffected, and carry MSL Rating 1 (Unlimited). Compliance certifications are equivalent across all three parts.

Q: Which substitute should be selected for new product designs?

A: CDCVF2509PW is the appropriate choice for new designs. It maintains Active product status, ensuring long-term availability and manufacturing support. CDC2509CPW's Not For New Designs classification restricts its use to replacement and legacy applications only.
