CDCF5801ADBQ PLL Multiplier/Divider IC Equivalent & Substitute Parts

Part Overview

The CDCF5801ADBQ is a PLL Multiplier/Divider integrated circuit manufactured by Texas Instruments, designed for clock and timing applications. This device operates at frequencies up to 280MHz and supports multiple input and output signal standards including HSTL, LVPECL, LVTTL, LVDS, and SSTL. The part is currently in Active product status with 2000 units available in stock.

Identifying equivalent and substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or design phase transitions where alternative qualified components may be required while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCF5801ADBQ is determined by strict equivalence across the following critical parameters:

• Identical base product number (CDCF5801)
• Matching package and case specification (24-SSOP, 0.154", 3.90mm Width)
• Equivalent electrical specifications: frequency range (280MHz), supply voltage (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C)
• Compatible input/output signal standards (HSTL, LVPECL, LVTTL, LVDS, SSTL)
• Identical functional configuration: PLL Multiplier/Divider with 1:1 input-to-output ratio and differential output capability

The CDCF5801DBQ meets all substitution criteria as a direct equivalent part from the same manufacturer and product family.

Parameter Comparison

Engineering Selection Recommendations

The CDCF5801ADBQ is the preferred selection for new designs due to its Active product status designation. This classification indicates ongoing manufacturer support, continued availability, and full qualification for production applications.

The CDCF5801DBQ is electrically and mechanically equivalent and carries identical compliance certifications (ROHS3, REACH Unaffected, EAR99). However, its "Not For New Designs" status indicates that Texas Instruments has transitioned this variant away from active development. Selection of CDCF5801DBQ is appropriate only when existing inventory must be utilized or when design modifications to accommodate the Active variant are not feasible.

Both parts satisfy identical regulatory and environmental compliance requirements and are suitable for applications requiring ROHS3 compliance and operating within the specified temperature and voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can CDCF5801DBQ be used as a direct replacement for CDCF5801ADBQ in new designs?

A: CDCF5801DBQ is electrically and mechanically equivalent to CDCF5801ADBQ. However, the "Not For New Designs" status indicates that Texas Instruments recommends using CDCF5801ADBQ for new development. Substitution is technically valid but should be evaluated against long-term supply and support considerations.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 24-SSOP package with identical dimensions of 0.154" × 3.90mm width. PCB layout and footprints are interchangeable.

Q: Do both parts support the same signal standards?

A: Yes. Both CDCF5801ADBQ and CDCF5801DBQ support identical input standards (HSTL, LVPECL, LVTTL) and output standards (HSTL, LVDS, LVPECL, LVTTL, SSTL).

Q: What is the significance of the product status difference?

A: Active status indicates the manufacturer continues to produce, support, and qualify the part for new applications. "Not For New Designs" indicates the manufacturer has discontinued active development but may continue limited production for existing customers. For long-term supply assurance, Active parts are preferred.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry MSL 2 (1 Year) rating, requiring identical moisture control and storage procedures during handling and assembly.

Q: Can these parts be used interchangeably in existing production?

A: Yes, provided the circuit design and PCB layout accommodate the 24-SSOP package. The electrical specifications, signal compatibility, and compliance certifications are identical.
